Engine oil LIQUI MOLY or Castrol
this oil is fantastic. the car runs PERFECT. it is a bit pricy but i dont really care. i've used it for +60k doing oil changes every 5k miles... as the report shows, the engine is WAY better than perfect.
I have been using liqui moly 5w-40 in my 2009 2.5l for the past 30k miles and i think its the best oil. recently i have discovered their MoS2 anti friction additive and put that in my last oil change. the car runs very smoothly and should last a long time with its strong wear protection. also the car consistently achieves good MPG.
The engine with the new oil runs so smoothly, I can literally stand a coin on top of the intake manifold and the coin won’t fall.
There is few more approved liquimoly, amsoil I personally use 5w30 liqui with oem filter every 5-6k miles
the info is correct. I find the Castrol and Mobil 1 most consistently at Autozone. The Castrol is called Edge now, I think.
I have an mk4 2.0 Jetta with 87.000 Kms (54.000 miles aprox) and when I bought it it came with 20W50 Quacker State oil in it... I knew it was not correct so I change it with Castrol Edge Synthetic oil... The guy at the shop told me that since VW engines run on high temps the recommend grade was 5w50... So far the oil has been great... There is zero oil consumption, the engine runs smooth and the temps are stable...
Just completed my first hands-on oil change on the GTI; used the German 0W-30 Edge, since VW still owes me one more filter and Castrol oil change in a few months.
A definite 'no' on that. VW says no and it's been shown many times. The factory fill is plain old off the shelf oil (generally Castrol).
Related test in European car, changed all fluids and spark plugs saw gain in HP.
Have my best experience with Castrol 0W30 (European $8.99/qt) Minimal lifter noise and run it 5k between changes. Also, use OEM oil filters.
