Hey everyone: The BB is getting it's first oil change since it arrived. I'm thinking a good organic oil would be appropriate for this vintage motor with 121K on the clock.
The service records I have are not specific about what has been put in before. I use Syn in every other car but I think it might be overkill and make it leak even more. This should be fun! |

I prefer a lighter weight synth like 5w40 mobile 1 euro blend. I find it takes the heat away better probably due to a larger volume of oil moving through (remember these are oil cooled). Synth also survives hot spots much better (critical temps in the 300s rather than the mid 200s). Thinner oil also gets to everywhere in the engine faster on cold starts and that is when the damage is done (thus the love of zddp, whether that benefit is real or not is also a huge area of debate).
That said, if you have a leaker, synth and thinner probably isn't for you. If I were to use thick dino, I would change it pretty frequently on an old air cooled engine, at least keep a close eye on it. |
