I been using mobile 1 from the day i got my car...but know i been thinking about doing a switch or should i just stay with mobile 1?...im thinking of running a different oil setup..my car has 100k plus miles on it..any good recommendations?

 

Im sure you'll be fine by switching back to regular oil, or a different brand of synthetic.

 

As RTGS400 mentioned, you should be fine with whatever you might choose.

All a matter of what you want to achieve with a switch, performance, mpg, better feeling, saving money with an extended change with something else.

For me, I am a person who is willing to shell out $$$ on good oil that will give me better performance and have an extended drain. That is why I use a German Castrol 0W30.

Let me know what you are aiming to acheive, as I probably have some good ideas for different oils, brands, weights.

 

I like Mobel 1 Synthetic Extended Performance which says will last up to 15,000 miles.

 

if what you are using works well, why change?

 

I've heard good things about Pennzoil Platinum, and these days M1/Pennzoil Platnum/Castrol Syntec are all Group III hydrocracked oils, not a true synthetic like Red Line or Amsoil.

My LS is running M1, just for longer drains. I usually run Chevron in it.

 

I would use Pennzoil Platinum or Valvoline Maxlife Synthetic.
