Engine oil VALVOLINE or AMSOIL

Amsoil 10-30 my dad's an amsoil dealer

Amsoil VW Approved European 5w40 is a great oil! Amsoil has a gurantee and no one esle can challenge that they are any better in quality or protection. Their oil was designed for long drain intervals and have superior protection.

I use Amsoil Heavy Duty Diesel marine and truck oil.. it's preety good.. should be TDI friendly.

AMSOIL was my race sponser, and I've used their products in all of my racers including the SC'd 2000 4Motion. That being said, I wouldn't recommend running any engine oil ; including high-grade synthetics, over 7000 miles.

i use amsoil 5w30 love it

i use valvoline 5w 30 and it hasent done me wrong...yet

I also have a 2.0 and run the valvoline synthetic. I started after 2500m and am currently at 29k. No scientific results here other than keeping track of mileage in a little notebook and looking back at the first month compared to the most recent - I'm averaging about 7mpg more.

All these problems are not present in the Valvoline SuperSynth 5W-40 sample. Furthermore, the results from this Valvoline are well below the Universal averages for this engine. This suggests that I should be able to run this oil for at least another 1000-2000 miles and still get an excellent report out of it! With it, my engine runs bit smoother and quieter especially at idle. At high engine speeds the engine feels more responsive and more lively. Another difference is that with Valvoline, I am observing improved efficiency. My 2.0 broke its own record of fuel efficiency: 34.3 miles to the gallon on high way. The improvement is 3.3-3.9 miles per gallon compared to Mobil1.

Interesting. I've been using Valvoline synpower 5w30 since 5k miles, currently almost 75K miles.

I ran my 2K beetle for 21K miles on Amsoil 5-3o/5w-40 and milage went up 7% and started awsome when it was 0 degrees out . Now I have a 2005 Jetta and its next for the 5w-40 @ 5K oil change .
