From what i know my car had regular oil put in in. Is it a good idea to switch the oil to mobil 1 Mobil 1 5W-30 when the car has 110.000? or something can go wrong after the oil switch ?

 

I switched at about the same mileage, and now have 240k, so no, it is fine.

You might try mobil1 hi mileage oil 1st. its got seal swelling agent in it. Then do the regular mobil 1 on the next change.And if your going to 5w30 check for consumpion & chain rattle on cold starts. I had to go to 10w30.

 

I'll be fine. Just do it. As with Nmexmax, I did it also around the same time. I now have 222k.

 

u gonna be okay, go for it.

 

Thx guy i will change it to mobile 1 when it stops raining over here lol

 

i switched over to M1 EP @ 126K and developed nastly VC & TC cover leaks a few months after.
