okay so i had my oil changed today, and when i got back in the car i noticed the type of oil they put into the vehicle. My car calls for a SAE 5W-20 or 0W-20 and they put in 10W-30, now there is this knocking noise and the engine is louder(my car is a 2007). I took it back to them and told them about it, and showed them the owners manual and the cap on the engine says what type of oil to use. so they drained the oil out and replaced it twice the noise is quieter but it is still there, its a brand new car with only 2990 miles on it.
they called around and everyone they talked to said the noise will go away once the lifters are back to there prime, putting in the contempary oil stripped the lifters of the sticky stuff that the synthetic oil put on them, they said it will take awhile but to speed up the process to use and additive called slick 50, they said that came from a TOYOTA tech. Is it safe to do this or should i not ? i dotn want to mess up my warranty....

believe it, they said the same thing..wouldnt have made that noise just from oil change, but shiiit when you started it you didnt even know the car was on thats how quiet it was. thats how i knew something was wrong and reading my tag, said which oil they used.

Give it a chance. Hard to believe that it would have made that much difference. Sounds like a dealer did the oild change, or was it some oil change place? If it still makes lifter noise then take it back to the dealer and have them replace the lifters under warranty. However, I think you will be all right but wait and see.

SAE 5W-20 is used in many vehicles these days because of the close tolerances the engines are machined to. Anything heavier may cause problems. This has been an issue with Ford for quite some time.

I don't think your engine was hurt, but who who ever put the wrong oil in the engine may have violated your warranty terms if the oil was something other than what is specified in the owner's manual or factory service bulletins. If the dealer did it, the potential repair could be on their dime.

It can be only suggested that you keep an eye on the situation and document things very well so you will have some recourse in case the engine does develop problems down the road. Slick 50 may help the situation, but I don't think it is a cure. If there is any damage, it has already been done. But, the only way to tell is to tear into the engine; which should not be an option with only 2990 miles on it. Let time dictate if there is a problem. My best guess is that you'll be OK and nothing serious has been done. However, play it safe and keep a close eye on things.

One final thing. I don't think your Toyota has lifters since it should be an overhead cam engine. If someone told you the Slick 50 would quite these engine components, I think they were probably selling you a bill of goods...or an expensive bottle of Slick 50.

Many newer vehicles have a sensor that tracks how long it's been since the last oil change. The guys at the shop are supposed to be knowledgeable enough to know which vehicles have these, and to know how to reset them. Sadly, many of them don't know which vehicles have them, or, if they do know, they forget to reset them. Therefore, the sensor thinks the car is still using old oil and it turns on the oil change light.

well talk to your local toyota dealer if they say yes get there information and go ahead and do it... Although i would write a formal complaint to whatever company changed your oil. I think that products like slick 50 do coat engine parts with a thin oil film then they get quiet, but dont void the warranty

hi... letting someone do an oil change or preventive maintenance on a vehicle, it is just wise, to get in writing what is going to be done, what parts are going to be replaced if any, and any misc,, before starting any work to it... in your case , an oil change, oil viscosity ,brand , should have been discussed and kind,brand of oil filter. and if you strictly just want an oil change, thats all they are going to do to your vehicle. now, if they check your air filter , other fluids or other stuffs etc.etc.., and you did not discuss this prior, you should yell 'stop' to the mechanic performing the job. i suggest to bite the bullet and consider a lesson learned.
if you want to use slick50 which i recommend highly now,,, there are two kinds. one is for low mileage or new car like yours.(do it now) ,and the other is for vehicles over 100k miles which you dont want at this time.
and remember there is no need to over rev an engine if you dont race it. over reving it will drop the life of an engine. :)

read the owners manual book and only use the recomended oil grade,
Your car is under warranty ,so don’t worry, consult your nearest service centre and inform them. And don’t forget to claim your free service and repairing
