Engine oil Castrol or AMSOIL
i drive a 95 jetta vr6 i currently running mobil 1 10w-40 but i been hearing alot of good things about this new castrol edge thinking about switching to the 5w-40....im hoping i feel a difference
i run 20/50 Castrol year round. it actually reduced the burning and smoking of oil on start up, unlike Mobil 1. i'm glad i switched over.
It seems 15w-40 is the standard diesel weight. I bought Castrol last time because it was on a good promo sale.... 5 quarts and filter for $5 (after rebate).
I recently swapped to German Castrol 0w30, it starts high 30 and stays high 30, so far, I've experienced no oil loss - but it's too early to say, but it makes sense.
I have been using it for about 15k km and two oil changes and have noticed allot less burn off compared to the dealer filled castrol 5w -40.
The only oil I used in my Audi before Amsoil was Mobil 1, and this far surpasses it.
You will not get better, check the results yourself, I gained 9hp and 6 ft lbs of tourqe and increased my gas mileage per tank 35-50 miles.
for the ow-30 im guessing your talking about german castrol. thats what im using right now and it works well
IMO most anything is better than Castrol!
But from my experience with it, it has made a difference in several of my vehicles (not only VW).
