    My son just bought a nice 2003 Passat 1.8T wagon. The previous owner was running synthetic but I'm not sure what weight. I've got a new 5 quart jug of Mobil 1 10w30 sitting on my work bench. Does anyone see an issue running the 10w30 Mobil 1?

    Being very (emphasis on very) low on cash I have not been looking forward to paying for my oil change. Its been 6000 miles now though so it really needs to be done. Currently im running 5w-30, but amazingly enough i found 4 quarts of sealed Mobil 10w-30 in my garage. Will this work in a V6? And...

    The manual and Bentley guide recommend 10W30 over 5W30 oils(2002V6PassatAuto). They really make it seem that there is a real big difference. I could not find 10W30 at my auto store tthe other day so I used 5W30 Castrol . Is there a big difference and can it cause a big problem? I am thinking...

    I buy the Mobil-1 10W-30 because is what is available in Phoenix, AZ. The 1999 Passat V6 Owners Manual recommends 10W-30 for warm weather, and 5W-30 for cold weather. From reading some of the posts, I get the impression that Mobil-1 10W-30 is incorrect for the Passat V-6. I've never seen...

    Just changed the oil on my 2001.5 B5.5 Vr6 with Mobil 1 10w30 as it was the only synthetic the Advanced Auto had this morning along with a K&N filter (ONLY damn filter they had for the Vr6 period). Now I've noticed an increase in valvetrain noise, lifters, etc. I haven't driven it yet, so I am...

    Is running Mobile 1 10W-30 oil safe in our cars? I used it last oil change, and I plan to use it again this oil change. Atomic Alex, your comments would be appreciated :D. Anyone else is welcome to respond as well. I would like to hear from people that have used it for an extended period of...

    I was in a local VW dealer for a warranty catalytic converter replacement after it blew right out of the mounting flange on the turbo housing, so I figured I'd ask them to change the oil because it was nearly time. When picking up the car I asked about their choice of oil and to my :shock...

    Yes it's another oil thread (sorry). I've read a lot of the others, and there always seems to be a lot of fretfulness over getting a "0Wxx" or a "5Wxx" and is it a 30 or 40 or 50. Always living in temperate states (TX, CA, HI), I've pretty much stuck to good old 10W30; clinging perhaps to the...
