Car Forum / Volkswagen / Water Cooled Volkswagen Cars / August 2007? GTI: 5W-30 instead of 5W-40 ?
2006 GTI (2.0 turbo) I found that the VW dealer put in 5w-30 instead of 5w-40 today at my third oil change. I told him the manual says the oil must be 5w-40, but he was unconcerned. The receipt says he used Castrol SLX Professional OE 5W-30. I bought a quart of the same from that dealer, and the container says: API Service SL/CF; VW 502 00 / 505 00 / 505 01; ACEA: A3/B4, C3; MB 229.51. I'm sure that's very high spec oil, but what about the high ambient temp such as the high 90s that I'm driving in daily now? Isn't that what the *40* is for? Should I be concerned? Thanks, Roy >2006 GTI (2.0 turbo) > [quoted text clipped - 9 lines] >such as the high 90s that I'm driving in daily now? Isn't that what the *40* >is for? Should I be concerned? Take a deep breath and relax. You have nothing to worry about. | >2006 GTI (2.0 turbo) | > [quoted text clipped - 11 lines] | | Take a deep breath and relax. You have nothing to worry about.

I am persuaded that 30 (5W-30) is ok for up to a 100 degrees. I appreciate the links. Thanks. > | >| >2006 GTI (2.0 turbo) > | >| > [quoted text clipped - 34 lines] > degrees. > I appreciate the links. Thanks. So why do some VW manuals (e.g. 2003 Passat GLX) specifically call out 5W-40 oil, and not just for hot climates, either? -- Mike Smith .... > So why do some VW manuals (e.g. 2003 Passat GLX) specifically call out > 5W-40 oil, and not just for hot climates, either?

Probably as a roundabout way to getting people to use synthetic oil. Signature------------------------------------------------------------------------ Timothy J.

I see that the manual may well consider it OK, and if so don't worry at all. However you did learn one thing. The dealer does not care. If the dealer did, they would have taken the time to point out in your owne's manual the specification and put your mind at ease then, or replace the oil. Consider that dealers usually change more and are, in geneal no better or worse than indipendent mechanics. You should consider going to a local independent (not a chain) mechanic. You do not need to have maintenance work done at the dealer to maintain the warranty, you just need to keep it documented. SignatureJoseph Meehan Dia 's Muire duit |
