Engine oil Castrol or PENNZOIL

any oil that meets the LL-01 standard will do, buy whatever is on sale. Castrol Edge Euro 5w30 is fine, Mobil 1 euro synthetic, whatever.

I am tuned in WI and running Pennzoil Ultra Platinum 5w-30

My conclusion was to use the best Castrol in the gold bottle. Of course, YOU must use the specification of weight recommended by the owners manual for the temperature range you expect to be operating in.

The gallon of Castrol is the same whether you buy it at CT or Napa.

Personally I always run Castrol and it's done me well, even in older cars that had been a bit battered.

Been using the molygen one, noticed a small reduction of oil consumption and better idling than Castrol (VW recommended)

I use the blue bottle 5w-40 on my 2.5 Mk5 Rabbit.

Runs quieter than when i used Castrol High Mileage.

About $22 for 5 Qts. of Castrol (you can buy it on Amazon or at Walmart for a decent price). Filter is about $4.00 or more if you buy a premium filter.

I've used mobil 1 20-50 for the last three oil changes and had really bad ticking noise from the head. This last oil change I used casterol GTX and have had a lot less ticking since. I'm no longer sold on mobil 1 for the rocco.

Stay away from the stuff that the dealer puts in, the Euro Car formula(5w-30 i believe) that Castrol makes is a Blend, meaning not fully synthetic and it shears and burns really quick.
