Sorry, it's another Oil Thread !!

To answer the original post-Yes, I’ve been using Westway Oils in my RT’s & cars for several years. They produce a wide range of the new spec. Oils needed for today’s engines.

The Camhead is basically the same as a car engine, with a dry clutch & separate gearbox, therefore, fancy expensive motorcycle specific engine oils are not necessarily required.

If anyone is looking to save cash on Camhead oil, would you use a car oil rather than an expensive, over engineered motorcycle specific oil.

"Car oil is designed to work in the engine, besides the fact that bike engines usually rev a lot higher. You can buy a cheaper car oil with the same viscosity as a motorcycle oil, but it may not have the additives necessary to make stand up in a bike."

Yep, the only difference is 5w vs 10w, I'll live with that.

"It’s important to use the correct oil for your engine, but if for some reason you had to use something else, a 10W50 would cover the range demanded by an engine that’s designed for a 15W40 oil as the first number is lower and the second is higher. Equally, that means a 10W40 is no good for an engine that should have 0W10 (as the first number is higher) or one that needs a 15W50 (the second number is lower)."

Now there is a third choice, motorcycle, car or aviation oil. After all the Boxer engine came out of an aeroplane!
