What will the consequences be if 10W-60 LiquiMoly oil has been used in my car for few months?

 

Ahhh the old school way to protect an engine, really thick oil. It is possible that the oil will thicken up and cause some parts not to be lubricated and cause some kind of damage. Stick with the factory recommended oil. Someone I know used 20W-50 oil and needed a new turbo shortly after.

 

Its generally just how quick the oil will get everywhere in your engine on startup. Changing the grade means that your changing the specs to what the engine was 'run in' on. Everything pretty much wears into a good place, so if you change oil spes you are changing that wear pattern

 

I'm using Royal Purple 5W-30 now. The 10W-60 was used for few months before. The question was, did it affect the engine parts that much?

 

I wouldnt worry about it. Though I WOULD be using 10w. I used 5W-30 and it burned up so fast that I spun a bearing b4 i knew it

 

what brand were you using ?

 

Anything you read here will be pure speculation. Why don't you have the oil analized when you change it next time, and then post your results? Assuming that you aren't experiencing any engine problems while driving, that would help answer your question better than anyone here can.

 

Indeed.

 

hes got an 04 so the oil burning shouldnt be a problem.

 

true. I was using Mobil1
