I am sure this has been hashed out here many times before and I don't want to start another oil thread but I be a newbie. Car I just purchased was rebuilt about 20k ago ('74 2.o) and the records show 15-40 weight has been used since rebuild and at all services. Now is this not a heavy diesel weight oil? I use this weight in my BMW 535i as recommended from factory, but a small air cooled VW mill using this heavy weight? Doesn't sound right to me. Clue me in please. Oh, engine is dual Weber's and a Web cam.
Thanks. |

The problem I have with mobil one in a t1 or a t4 is the cost. If your engine leaks, you're wasting more moolah than if you were running dino oil. Even more of a problem is if you have a lot of blow by or an engine breather system that isn't adequately filtered, your oil will get contaminated and you will not be able to take advantge of the extended oil change intervals that make synthetics more cost effective. I run mobil one in my daily driver and love it though (5w-30). It pours like water at any temp, and I change it every 5k so it is only a little more expensive (if at all) than a dino change every 3k. Synthetics are less prone to thermal breakdown which is a good thing in our hotter running air cooled engines. And they are probably more stable for cars that sit for extended amounts of time. So it is really a trade off I guess.
Once I get the PCV system sorted out on my (now) leak free t4, I'll probably go synthetic. Should be interesting to see if there are any noticeable pressure or temp changes. -Chris |
