Dealer recomends not using synthetic?
 

I searched but I could not find an answer.

I know dealers suck and all but I took my car in for it's first oil change today and the dealership recomended I do NOT use snthetic oil and I use a regular oil which is suggested by mazda themselves.

Ruling out the fact that the dealership is feeding me a big steaming plate of bullshit, why would this be?

We have way too many oil threads... this being one of them. You must search harder. I cannot link you to the thread cuz im on my phone but you can find it.

Top choices for our motor...penzoil plat 5 30, rotella 5w40... Both synthetic, check out bob the oil guy and search this site.

I know we have a lot of oil threads. As I found many searching, but none that answered my specific question. I did search and seen what oils were best as I gave the dealer Penz plat to put in my car today. He just gave the reason that our turbo's have a potential to smoke easier on synthetic oil.

Because this

:smileeek:

Is a fun app though

I went pennzoil ultra at 1k and never looked back. My stealership just sent me a coupon for a synthetic oil change so I call BS from your stealer.

Oh I see, he doesn't want you to get a free new turbo or vented valve cover lol.

Turbo doesn't usually smoke until you are cat less I think, at least that was my experience...now I'm 5w40 and no smoke....so you could always do that, or let them put shit oil in there.

your dealer says not to use synthetic because Mazda says not to.

now go use synthetic, because there's plenty of data proving te beneficial.

/thread

You sir win the interwebz.

I guess I was just trying to see if anyone maybe had the data from mazda backing up their claim.

You've fallen victim to the same assumption many of us made when we first bought our cars: The assumption that because the dealership sells the car, they also know anything at all about it.

It would be nice if dealerships could be a beacon of knowledge and information about our cars. The truth is between lazy/bullshitting techs, or crappy corporate communication/education, the average Mazda mechanic doesn't know a Mazdaspeed from a hole in the ground.

There's a few and far between that do, but the general rule is don't listen to anything they say until you can verify with credible sources.

It's funny cause my dealer told me back in the day that they use a 70/30 blend. Fuck dealers use penzoil plat 5w30 and nothing else.

they probably want you to do as many oil changes with them as possible

They're gay

In South Africa if we dont service though dealers we lose the warranty and service plan.

and they use the cheapest oil they can :/

fuck the dealerships opinion. put your motor on that Rotella T6 and tell them to kick rocks

Rotella T6 >>>> PP just sayin. shits better than Amsoil Euro based on Oil Analysis which is saying A LOT

dealerships dont always know best. they are just another group of people working jobs to pay bills, they are by no means experts...especially the advisers, which is who most people talk to.

personal experience... My dealership said synthetic was bad for my car and not recommended...then on my 5th service, same adviser, same dealership at 15k miles...they told me synthetic was recommended and thats what they were going to put in the car. :ponder:

They say that since when the car was built/being tested they use synthetic blend and they do not have any data for how the car will operate with full synthetic

Been on full synthetic since 1000 miles. 5W-30. Fuck them bisches as they know absolutely DICK about our cars in particular.

Switched the last car over at 1500 miles and this one will be the same. Gonna look into the Rotella stuff I keep hearing about.

why people continue to listen to the dealerships i will never know

please people, buy your car, then never ever ever go back unless you absolutely have to

next time your change your oil pour a gallon all over your car. it's good for 100hp since it makes your car all nice and slick.

Since when the hell did mazda say not to run synthetic? My damn manual on my speed 6 states 5-30 syn then 5. something quarts... that dealer is a moron. Probably thought you had a regular 3.
If they sell BG products (like 95% do) ask him for a "performance oil change" they add a SYNTHETIC additive to the oil called MOA to supposedly help the oil.. if he sells you that then my response would be.. "your dealership is trying to screw me.. u say synthetic is bad but want to sell me a $75 oil change with synthetic in it" then talk to the service manager and get a few free oil changes for his ignorance. Stick with the synthetic the oil in these cars takes a beating.

Mind you, I bought my car from several hundred miles away, not my local stealership. Just as well, since my local mazda dealer, an actual Mazdaspeed dealer, scared me.

My first trip there was just to pick up a CX-7 stubby antenna. While leaving Parts, walking out to my car, one of the CERTIFIED MAZDASPEED TECHS walked out to me and asked where I got that "bitchin cool front bumper" for my 6. He wanted one for his 6.

yeah.....


and that, my friends, is why I do my own maintenance & repair work.

I totally agree. After working in dealerships for years I hated even bringing my car in for warranty work. Check out my first thread... all kinds of issues with the dealer I think they had my car like 4 months out of the first year I owned it! I even diagnosed the damn thing for them! But noooo we have the best techs and they disagree.. well I was very happy to prove them wrong..lol
Just a word of advice to anyone that brings their own synthetic to a shop.. do yourself a favor and get a little bottle of oil dye and put it in one of the bottles. I can't even tell you how many times I would see oil changers and even A tech's stealing peoples Mobil 1 for their own vehicles. At least with the dye you can prove it, get your money back and ton of free oil changes in the future. I prefer to do all my own maintenance and installs. I have never brought any of my vehicles to the dealership for anything out of warranty.

Rotella T6 all the way.

This kind of shit still happens?? Some dealers just dont get it. Its no wonder the dealership service industry is in the shitter. I would like to argue things have changed and customer retention after the sale means something to people but I guess not. I work for a dealer and cant even imagine if one of my techs did something like that. Fired on the spot.. No warnings... There is no place for shit like this.

I completely agree about firing but there's a huge issue. The dealerships are required to have a certain about of guys trained in certain areas to be able to be an authorized dealer. It costs them a lot of money for the training and having to start over would cost much more than some oil. When I was at GM I was their only tech certified in all GM Platforms and for all systems. When I quit they kept me as a current employee on the dealer system for over a year so they wouldn't loose compliance! Whomever the hell was doing the repairs was obviously not certified to do so! Dealers used to be the pinnacle of a tech's career, now it seems guys only care about making their hours and nothing more. The owners of these dealers are just as responsible. The service department makes more money than sales so they don't care what it takes to make money as long as its profitable.

This is another reason I don't let dealers touch my cars. they have no fucking idea what they're talking about. Most of the techs are just computer reading braindead fucks with no real car knowledge or mechanical skills.

Damn I sparked a whole ragefest on dealers lol. As people have said i did not take their advice regadless and i gave them penz plat (recomended here). Hearing all this shit about dealers I am never going back.

All this hate is okay but there are still some at these places that have a clue and know how to fix a car. The flat rate system has ruined the techs that used to care. They are forced into making their time vs. taking their time. The whole system needs changed. The other problem is dealers turned the service advisor position into an admin job.. Not a service advisor... More about sales, cust service and paperwork. NOT working knowledge of a car. There are exceptions to this but thats whats happening.

i took my car in to the dealer and they used castrol snythetic in my car for my first oil change

i like Castrol synthetic its a good oil.

i see most ppl here us penz oil plat but castrol gets the job done its not like im taking my car to the race track any time soon anyway

This car messes oil up. Whats good in other cars, might not be good in this one. I think some analysis's guys did here showed this motor fucked mobil 1 up in like 1000miles.

The only oils I would use in this car are penzoil plat, or rotella T6.

I don't track my car either, however, you are talking about a direct injection turbo charged motor. It abuses oil just being what it is.

On the other note, I hate anyone else working on my car but me, or people I know. Most of those guys at the dealership/oil change shops don't know wtf is going on.

First service interval is 7500 miles. I got an oil change at 4000 because I'm anal. Decided since it's new and all I should take it to the dealer for the 7500 checkup. Get it back and notice the sticker in the window says next oil change "10459." Next interval is supposed to end at 15000. Go look over my receipts sure enough, they put non-synthetic oil in.

Dealerships suck. Find a lube joint you trust and have them do it. I used to do it myself but getting rid of old oil can be a pain. Not worth the $10 in savings.

^really? autozone takes oil for free...i do my change and when i go in in a few months to buy new oil i just dump it in their tub

I'm going to add to this. Idk where you all are (assuming majority are in the US), but where i live, the last time I did my own oil change it cost me $90 for PP oil/filter.

I had this argument with the dealership regarding regular vs synthetic for the free oil change program. What it came down to was that Mazda doesn't say synthetic is "necessary" for this car, ofcourse it's a better choice but not absolutely needed. The car manual doesn't state this either. Hence, the dealership is not obliged to use synthetic unless the customer asks to and using regular wont void any warranty issues either.

It just comes down to YOU, the user. IMO if my car was stock I'd just go with regular oil changes and not give a damn.

My buddy has a gen1 when they first came out in 07/08. It's completely stock, he drives the shit out of it likes it's meant to be driven, maintainence is done at the dealer and he hasant had a single issue with the car for the last 3 yrs.

So give this topic a rest already.

first i thought everyone knew you have to ask for synthetic oil, becasue the standard oil change is non-syn.

second i have heard from different places to not use synthetic until about 5000 miles because non-syn helps your rings seat correctly.

third- you could probably cheap out the first few oil changes because that oil should only be in there for 1500-2000 miles when its new. this is to flush out any metal shavings foating around from initial manufacture/break-in of your motor. OR just follow the manual and have metal shavings in your oil for 7500 miles.

4th - or you could ust check the other 9999999 million oil threads

i did my first oil change at dealer at 550mils due to its a new engine i wanted to get all the oil with the metal filings out from the egine making the grooves so i had to get that crap cleaned out asap! all new cars in my household we get the first oil change btwn 500-1000miles

I've been using synthetic oil with no issues since I first purchased my car (had 35,713 miles at the time). At 75,500+, I don't regret using synthetic. Sure, I had a smoking turbo issue resolved under warranty, but that was apparent soon after I got the car.

On another note, my synthetic oil changes have been done at my dealership. They use Valvoline, so I have no idea whether or not that's a good thing. So far, so good.

No Autozones around here, some quicklube places take it, but just a PITA all the way around.

I naively assumed the 7500 standard service interval implied synthetic. Why would 7500,15000, etc be listed as service intervals and the dealership put a sticker on my window for 3k? Because they didn't know what they were doing.

I've heard this too, but personally I think it's just an old wives tale. Crosshatching is still visible on most fuel injected engines at 100,000 miles so it's not like the rings "seat" a whole lot anyway (DI might make this worse though). The machining tolerance are usually pretty good on modern engines so ^shrug.

Changed it early anyway (@4k, 7.5k was the 2nd change).

I didn't start this thread, I was sharing my experience with the OP. :fing26:
