Engine oil Castrol or Shell

Have used the T6 myself for years in assorted VW's and Volvos with reduced oil consumption as compared to the VW 504 oils.

It isnt either mentioned, but I have used the RotellaT6 with good results. I did this for my first oil change after I bought the car used. Not sure what the previous owner used, but the chains quieted down quite a bit.

Shell Rotella T for the win - get it cheap at your local Walmart in gallon jugs. Side note on collapsed lifters - ATF Type F, added to the oil and a 5-10 min idle cycle before you change the oil can really help clean them out for cheap. Note, ATF has a lot of cleaners in it, and is thin, DO NOT rev it...just let it idle. Worked awesome on my old Coupe GT 5 cyl with horrid lifters.

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.

Mine doesn't use any, and it gets an italian tuneup every time I start it. Running Rotella T6 5w40

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

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.

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...
