Will changing the oil on my 6.2 void my warranty?

[Badass69]

I let the dealer change mine once..... made a mess all over under the truck and overfilled it. Filled the skid plate full of oil from the filter and then of course it blew out everywhere on the road..... and they didn't understand it's 8 quarts capacity and not 8.5. Yes change it yourself...... if warranty is your utmost concern use the 0W20 water they spec for them..... personally I like 5W30 Signature Amsoil in mine. GM specs 5W30 in the wet sump Corvette too....... and the LT1 and L86 are identical longblocks..... but warranty isn't exactly my number one concern lol. I don't even have a stock tune anymore lol. Wouldn't take much to make one though so I might do that... my stock tune currently only has the change of AFM off and the top speed limiter disabled.

GM only recommends what makes them money. They want a monopoly on what you buy for your vehicles and their owner’s manuals and propaganda are designed to affect that end.

Exactly.... like the exact wrong way to break in an engine and make a roll of the dice if you get an oil burning disaster or not lol. But that's not just GM.

They are a for-profit corporation. Is this even a question ?

Do you trust the internet conspirators or GM?

 

Do you trust the company of engineers that has made, tested, produced, and repaired millions of engines? Or the guys that have no certifications and have probably only worked on a few dozen engines at most?

 

I trust GM and use the oil spec and weight that they recommend for your vehicle. Technology constantly changes and advances and the old wive's tales that may have been true before aren't necessarily true anymore. You won't void your warranty by changing your own oil.

I would definitely use the recommended weight oil, but I wouldn't be afraid to change it myself. Like I said before, just keep records.

As others...run your personal choice of 0w20 and filter, and keep records/receipts in the event it ever comes to needing engine related warranty work. They may want to see that you've been keeping up on oil changes.

Because I want to get all the metal shavings out and I want synthetic. GM won't change until oil life is below 20%

Bingo! I changed mine at 500mi, 1000mi, and then let the GM do it.

Not GM but Nissan. Wife took her vehicle to the dealer for an oil change in the morning. Came home parked in garage, ran an errand in the afternoon, and backed into the garage. Next morning when I left for work I see a long slick coming out from under the front. Drain plug was only half in. Stopped at the dealer during my lunch break to let them know what happened and the service manger gives an unapologetic sorry and hands me a 50% off oil change coupon and seemed to try to get me out the door as quick as possible before any of the other customers could pick up on what I was talking about. We don't use that dealership anymore. It's hard to trust strangers working on your stuff sometimes.

Generally, the public is unaware that it is illegal for a vehicle manufacturer to tie the warranty of its product to the use of the manufacturers own brand of lubricant. Federal law seeks to ensure competition within the marketplace and that specifically includes guaranteeing continued warranty coverage outside of the OEM-branded lubricants. In short, you have the right to use the oil of your choice. If the lubricant did not cause the problem, the OEM warranty cannot be voided, period

Very helpful - Thanks Mike. Rick
