Re: How many quarts and what weight?? (ntrldub)

Hehehe, thats funny, my girl is addicted to that movie too...in particular Vin Diesel, but we've watched it like 3 times since we've had the DVD...eheh
So anyway, 4 quarts of 5w30, I could be wrong but I don't think Mobil makes 40?? Keep the responses coming, I'm gettin' the oil today....thanks.

Any of those will do for the 1.8T. Ideally you want 5w40, but that is hard to find. 5w30 is an easy find and probably the most commonly used. I know the search is down but there is tons of info on the 1.8T forum.

5w30 is what it says in the manual. With a new car, the thinner the better. Less drag. You need 4.5 quarts assuming you're changing the filter too.

Re: How many quarts and what weight?? (SlickShoes)

why do people always want to go heavier? Mobil 1 is available in 5W-40 only as Mobil Delvac 1, a Diesel oil. You do NOT want a spread of 45 weight points, as in 5W-50, because the additives that are used tend to break down quicker.

quote:[HR][/HR]The wider the viscosity spread the greater the use of polymers to achieve that viscosity spread. Polymers can break down and form deposits that can increase engine wear and decrease engine life so, generally speaking, the lower the viscosity spread the more durable the oil will be. Remember to use multi-viscosity oils with the smallest viscosity spread you can get away with for the temperature range in which the vehicle will operate.

My personal recommendation, time and time again, is BMW full synthetic 5W-30. I have been using it for over 35,000 with virtually no engine wear based on a compression test I just performed with 62,000 miles on the car. On top of that, it's the cheapest synthetic out there at $3.80 per quart (Wal-Mart store brand not included).
