Engine oil VALVOLINE or Shell
Hey I've got 145K miles all but the first 5K on Shell Rotella T from Walmart. I go 10 to 12K between changes and I'm running Big injectors with the IQ dialed up. No Probs...
My '03 jetta tdi just turned 84000, I have used the rotella synthetic 5-40 the whole time. I change it about every 7,000. I'm in the northeast. Last year it got down to 10 or 15 below quite a few times. It sounds like someone shaking a buckets of marbles when I first start it, but it smothhs right out and allways starts. Rotela is ok by me.
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.
on both my current 1.8T VW'S i use Valvoline Synpower 5w-40 Full synthetic- it's an oil that is approved by VW...and has all the right cleaners/additives in it.
Lately, I've been using the Rotella Synthetic 0w40 which is available at Canadian Tire. It conforms to the required specifications for the non-PD engines.
Canadian Tire sells Shell Rotella SB full synthetic. Great for our TDI's....
Another option is the Shell Rotella T synthetic 5w40. It's not a PAO base stock. But it's $13 a gallon, for cheaper oil changes.
