Engine knock, will warranty be void?
 

Last Monday coming back from work I heard a knock that at first I hoped it was a loose bolt on the headers or anything other than a knock lol after showering I decided to go back out and examine the car. I turned it on and ran inside to get a beer and when I came out it died by itself and won't turn back on. I checked fuses and the oil and anything to make sure it wasn't engine failure but I'm positive it is.

Anyways I used either Eneos sustina or motul 300 0w20 most it's life and just this last oil change I decided to try out amsoil 0w30. I changed the oil before due intervals, about every 4 months or 5k miles. The last oil change was maybe a couple weeks before the car died. Now I'm paranoid that the dealer might use the 0w30 oil against me to screw me from covering the engine which I'm fairly positive isn't my fault or the oils fault as many others use different weight oil. The car has 49k miles and I have all the receipts that are dated from the oil and oil filter I have purchased since buying the car. Also the car has no mods that could have caused it either.

I usually use it to drive from work and back, I did participate in a drift even last year and have fun with the car here and there, but nothing like what other members do with their cars every other weekend or so. Sorry for the long paragraph but If you have any input I would appreciate it, thanks.

Read the manual about the oil.
Go to the dealer about the warranty.
Good luck.

They won't really tell the difference between 0w20 and 0w30, but to be safe you need to put the car back to stock and put the stock tune (if you're running any sort of tune) back on to even have a snowballs chance in hell of getting a warranty repair. Assume the dealer will do everything they can to prevent you from getting a warranty repair.

Engine knock, will warranty be void?
 

Yeah, I'm not running any tune or anything other than suspension mods which I switched to oem. I'm fairly positive it won't be a cake walk with having them cover this

The dealership will request maintenance records and will see the oil you used. They will want all the records of past oil changes if they weren't done by the dealership, so bring everything you have and hope that the problem is not oil related- it could be a lot of things though TBH it doesn't sound good. Good luck, let us know how it goes.

You'll just need to pull all your maintenance records to make sure you have all your ducks in a row. Other than that, you should get the engine repaired/replaced under your 60k/5 year power train warranty. Not sure if 0W-30 on the receipts might hurt you though for improper oil usage.

Yup, I have all the receipts of the oil and oil filters I have purchased through out the ownership of this car and currently the usage of 0w30 oil is what I fear might void the warranty, also to note I have a 100,000 mile or 7 year powertrain warranty not that it makes a difference lol but I'm glad I have it either way. I know it won't be easy with Toyota but it's worth a shot, and honesty I really feel like it's a manufacture issue especially seeing many with blown engines without any mods. And I really tried my best to take care of this car other than sometimes driving it for what it was designed for.

I should be calling Toyota tomorrow and see where it goes from there. Thank you for the replies thus far and I will keep this thread updated on how it all pans out.

Too bad your car's engine is acting up ..... :(

So, you lost me ......... do you have an aftermarket header installed .. ??

No I don't, I was just basically saying that I was hoping the knocking sound was anything else other than an actual engine knock lol

How many miles since the last time you used 0w20? If less than 7,500, maybe you can "lose" the records of using 0w30?

Please, for the love of god, read the manual about oil weights and what is acceptable...

Well, like said above, just take it into the dealer and let them sort it out.

It doesn't appear you have done anything wrong that would hurt the car.

Please keep us posted.
