Engine oil Castrol or Mannol

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.

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!

I have been using Castrol 0W30 European Formula all year round and it offers great protection in the coldest cold and the Highest Humid Heat. I used to use Mobil One 0W40 but it seems my car likes the Castrol 0W30 better since it runs smoother and gets a tad better gas mileage.

i use castrol 5w30 syntec edge. advanced full synthetic.

I use castrol syntech 10w40.
