10w40 or 15w50?

Thanks for this information! I’ll look for the Mobile1
 
You should get that period key fixed on your laptop.
 
The 60 weigh was actually a mistake but I kept it tried oil change with 60 and it was too thick of the engine , gas consumption went through the roof . went back to 50 weigh and just to get rid of oil without throwing it out ,included it in oil change and was good . Fuel consumption went back to normal but I noticed transmission made less noise when shifting. So went through all the 60 weigh and I'm back to 15-50 Amsoil and all is good . Waste - not , want - not !
 
Is this the one? my Silverback will need an oil change soon
 
Motul is by far some of the nicest fluids and stuff you can put on or in your vehicle regardless of how many wheels it has.
From high end brake fluid to fork oil... Imo it lasts longer and performs better at the end of its life and is not much more $.
But on the flip side my vintage bikes don't car as long as the fluid level is full.
 
That comment from @Mongler07 re his vintage bikes got me thinking.
Getting back to basics now.
When did Castor bean oil stop being used in combustion engines?

I leant a lot about oil then and now after Googling that question from a great Aussie oil company Penrite still going gangbusters since 1926. Far too good and long a story to post in entirety here, so happy .pdf reading.
