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.
Best Engine oil for Volkswagen Jetta
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.
i use 5w30 in mine and it runs great. really quiet.
I have been using 15W-50 Mobil 1 in the '92 Jetta for the past 130K miles (it has 264K miles total on it !!!). It doesn't leak or burn a drop and it is all original (best motor I have ever had!!!).
I recently put in Shell Rotella t, 15w 40 and it seems to work a lot better than the castrol 15w 40
I'm currently using Castrol Syntec 5W-30.
I waited 9,000 miles to change my oil most recently (with 36,000 total on my VR6 Jetta). The oil is Valvoline 5w-40 synthetic, which I buy from my local NAPA who now stocks it - finally. Bottom line - oil was still in very good condition - still suitable for further use - viscosity still well within 5w-40 perameters @ 14.1. Trace metals ppm were amazingly low for 9,000 miles of use.
3500 to 4500 on my VR6. always mobil 1 since 20k miles....now with 88k miles.
I change every 5,000 with Amsoil in my TDI. I like to change oil and keep tabs on everything under the car, so it's worth it to me.
For highway driving on a vr6, oil should be changed every 5k. City driving is 3k. BTW, go for 5w30 Mobil 1 Tri-synthetic. NICE!
