Engine oil Mobil or Lucas

Mobil1 0W40 is fine.

i've gone M1 0w-40 and love it but i might experiment this summer

I run M1 0w-40 and do that at about every 7k and it could prob go longer.

I'm going on 5 years 1 month using M1 0-40...I did try Castrol 5-50 once just to try it out, and the engine behaved itself...both synthetics and about $6-7/qt...

I'm sticking with Mobil 1 0w40; it's always been an excellent engine oil for my cars.

my gti loves mobil 1 10w-30. beenn using it for 170k with no issues

I run mobil 1 synthetic 0w40 all year round, with no problems. Best of both worlds

I use Lucas oil in my motor oil for 1990 VW 1.6L Jetta diesel. I started using Lucas Oil because a relative of mine has been driving a large semi for almost 30 years, and he, like many in the trucking industry, swear by Lucas Oil. Judging by the parts per million of metal present in my motor oil, my motor oil with 1 cup of Lucas Oil, was wearing pretty well.

The car itself is outstanding for the price, excellent quality build in my opinion. However the FSI engine has given a few of us some headaches. Mine performs great, except for burning excessive oil.

I've moved up to Mobil 1 5W-50 from Syntec 5W-40. So far I really like it. No noise on startup at all with it. I also use the monster oil filter.
