I know Oil doesnt make a HUGE difference but it can increase the life of your engine and i think the oil can also add a little to performance. what oil do you choose and how was your experience with it compared to others?

 

i put royal purple in my diesel and i noticed 2-3 mpg improovment and a noticable increase in power

 

I useCastrol synthetic unlock the horse power in mine

 

i use Mobil 1 on my mustangs.... and when my truck is due for its first oil change im putting the same

 

Just put the first batch of Royal Purple in last week, i think.

 

have a look at the most commonly discussed topics thread.... this topic is in there... i use AMSOIL

 

yeah i switched over to Amsoil from Mobil 1

 

Pennzoil Hi-Mileage 5w-30 winter, 10w-30 summer

 

Sorry I can't pick one from your Poll---I use Amsoil and have been for many years---20 or more, and never regretted it.

Started back in the early eighties when a guy I worked with, and also owned a gas dragster, convinced me of it superior performance and cost to mileage ratio compared to Dino oil.
