Title: Mobil 1 5-30 Post by: .. on March 13, 2019, 05:09:50 PM Friend has some he would give me if I can use it in the Valkyrie for my summer run to Taos and other places.
Yay or Nay?? Title: Re: Mobil 1 5-30 Post by: Jess from VA on March 13, 2019, 06:24:16 PM A lot of us use T6 shell 5-40.
10-40 is recommended. I am thinking a 30wt top is too thin, especially in long, hard cross country banzai runs, and in high heat (or even medium heat). And when I pour the T6 into the crankcase, it seems awfully watery to me as it is. It's like Mrs Butterworth lite, compared to say Amzoil 10-40 Bike specific, which is not watery at all. Now the Mobil 1 synthetic may be about as good as it gets, but.... it might be OK, in a colder climate. Title: Re: Mobil 1 5-30 Post by: Forge on March 13, 2019, 11:39:24 PM Warning! The 5w-30 is energy conserving and may cause clutch slippage from the additives!

As I think it is to thin especially for hot weather. You could use it by combining it with say 3 quarts of 15/40 Mobil !. Title: Re: Mobil 1 5-30 Post by: .. on March 14, 2019, 02:46:00 AM Thanks guys.

The first or "W" number is only relevant when the engine is cold. Synthetic Oils are thinner when cold and...much better at maintaining viscosity when hot which makes it possible for example, to have 5W50 weight with synthetics. To have a spread like that with "dino" oil a lot of "pour point depressants" would need to be added to achieve that number. If you used 5W50 it would be good under any conditions...cold morning starts or extreme heat riding. All pour point depressants do is prevent the oil from getting too thick when cold.
