Engine oil Castrol or AMSOIL

I ran Castrol GTX 10w-30 (yes, dinosaur remnants) for about 100-120k miles with zero consumption or other problems.

I have an 09 Jetta Sportwagen with a APR stage 1 ECU upgrade (since 2000 miles) and have 63,500 miles on the car. I have changed the oil every 10,000 and the oil is only down about 1/4 quart after 10,000 miles. I have done an oil analysis with Blackstone labs every oil change and the report comes back with the oil looks great and to extend the change to 11,000 miles! The report also shows my engine wearing betting than average.

Me...I'll stick to CASTROL EDGE 5w50...over a quarter of a million miles in an actual SCIROCCO.

I've been using amsoil for the past 2 oil changes. No complaints, car seems to idle a little better and cold start sooner.

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.

I also started using it in my bike after switching from Mobile 1, and it's the best thing I've experienced so far with the wet clutch, keeping the shifting very smooth.

I just changed the oil in my car and I used Amsoil 5w40 European blend. No complaints so far.

I wouldn't use anything other than Amsoil I recently purchased some to change my R's oil soon.

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...
