Please don't tell me it will void the warranty to use non dexos, that's insane.

IMO it's like Top Tier gas. Yeah, there are certain requirements the gas stations have to meet to have the certification, but of course, there are brands that meet the requirements but they don't feel like paying the licensing fee. I know Petro-Canada(which I use exclusively now because I work for Suncor, who is the mother company of Petro-Canada) used to be Top Tier but they were removed at some point. No idea why, but I think it's more likely that they don't feel like paying the licensing fee than they started using crappier gas. And in Petro-Canada's case, they have a natural patriotism advantage in Canada, kinda like Tim Hortons. Amsoil has some believers as well, so it's possible that they just rely more on those than paying for certification.

In the end, it's an oil thread and so it's just about using what makes you sleep well at night. Personally I am in the boat with others that's willing to pay a little extra for the peace of mind, especially if you only are doing it once a year.

If the oil change hurts your pocketbook that much then you very likely can't afford the car in the first place...

Ha, the car is paid for - it's not the money, it's the bs principle of it - it forces you to use Mobil 1 because of a sweetheart deal with GM. Standard M1 is not top tier anyway. I actually research this stuff and have for years.

There is no way they can prove an oil is dexos certified so denial of warranty would seem impossible

There's nothing "Special" about oil that carries the dexos label. Did you know, that even if you use GM's Dexos oil, they can and will deny a claim for excessive oil consumption?. Like the op said , it's a scam to get oil purchasers to use anyone's oil with Dexos on the label. If you don't believe us, call Blackstone and ask them whats so special about GM's oil....

Bingo.

At the end of the day, if an extra $20-$30 every few months saves the warranty on my $50k+ car, so be it... I do my maintenance myself so I'm saving labor either way (AND much more importantly, know it is being done right)...

ZX.

if you dont want to use it then dont. no one said you had to, except the warranty people at Chevy, go put gas station brand oil in your car for all we care. Its your warranty do with it as you will. this is not even what the original post is about

[ZX-10R]

Again it does not "save" the warranty vs something else that is correct viscosity/grade (full synthetic)

There is a religious factor this these debates. It's like those who say anything but a factory oil filter will harm the engine when it's been proven countless times RP, M1, and K&N filters perform better

i dont think anyone is saying there is not better products. we all know catch cans are good but they = Chevy have denied warranty's over them. so you do what your bank account can afford with your warranty on principal but most of us will give GM no reason to deny ours over something so trivial.

How would GM know your oil is dexos certified? Ever heard of such a test?

Ok so i will play this out. Say you go in for a blown engine and they ask you what oil do you have in the engine. Are you going to lie or tell the truth?
Personally i couldn't bring myself to lie but maby you can.

Bingo.

The guy in the thread drives a bloody Aveo. How many bucks do you want to bet that they saw redline more times than I can count with my fingers in that 400k km/250k miles? And do you see Aveos on tracks?

I wouldn't care as much about what oil I would put in, say, my old 08 Accord 4 pot beater versus my Camaro. When it comes to a performance car people will drive hard or even track, this comparison just doesn't work anymore.

Easy. They ask for receipts.

No receipts or receipts of the "wrong oil"? Too bad, so sad, but they can(not necessarily will) deny it.

Now I am sure you can get the legal team involved, etc. but for the little bit of extra cost, I don't think it's worth the time and effort involved. Besides, you never know if some dealer actually plays the legal game with you.

I doubt such a crazy scenario has ever occurred, or will ever occur. Your house could get mowed down by a tornado tomorrow, too. Dexos is a scam. Anyway, carry on, I'll keep using Castrol Edge. Great oil. UOAs prove it.

Within warranty, it doesn't hurt to play it safe. Again, how much risk you want to take is up to you.

And as I mentioned, it could be like Top Tier: it's a real thing with real standards, but there are brands that don't feel like paying for the certification even though they meet the standards. You might be able to find these brands yourself.

I don't think you can go wrong with Castrol Edge. I just wonder if the stuff in North America is the same as the European stuff, but Castrol just doesn't feel like getting a certification.

And note to myself: don't participate in oil threads.

I will probably come back to the recommended
Mobil 1 esp 0W40 dexos 2
I’ve read some topics on the net about fake dexos logo!
Don’t know what to believe now....

I just know and have seen how easy it is for a car manufacturer to deny a warranty repair. I don't disagree that there are plenty of quality oils that have proven Blackstone reports that are less expensive and more readily available that would perform fantastic. If something were to happen, I definitely am not in a position to hire an attorney to defend me and go after GM for repairs. While it's under warranty, I bring them my own oil and filter and pay them $15 in labor to change it so there is a paper trail. The last two times they didn't charge me anything because I always give them a 100% survey. The track spec oil is the only one that's "expensive" anyway. You can run Costco 5/30 for $2.49 a quart! There's also other great 5/30's like Pennzoil Euro L 5/30 Dexos for $22 for 5 quart jugs.

Cant agree more. Im not really concerned that I can void the warranty I think they would cover it but the dealer is the last place I want to be and hear then saying we have to replace the motor but don't worry your covered. It took me a year to allow them to replace my headliner because Im not a big fan of them touching my car. Im with you on this one.
