As it says.. Is it absolutely necessary to run Synthetic oil in my 103 Twin Can.. Or, can I use Valvoline VR1 high zinc Dino Racing oil?
the motor has a slight build.. Specs in the SIG..

 

Valvoline vr1 is what i run have a twin cam 107.I like it no problems.

 

I have been told run whatever you want, but don’t switch back and forth. You will probably get a lot of different opinions on this.

 

Not a darn thing says you must run SYN lubes. HD been running fine on HD 360 for a long time.

 

Do you know who makes Harley oil? Sunoco. Any good quality syn oil will work likes of amsoil, mobil and so on. Much better for the engine.

 

Run VR1 in both my 114 M8s and my 02 Twinkie.

 

Yes No Maybe

 

Thanks Larry... Your killing me.. Funny thing about that street signs is that my wife's name is Helaine and she's Sicilian so you can imagine how well the sign fits.. For me ...

I'm gonna give it a shot and see what my engine temps are like..

Thanks everyone...

 

I would not run non-synthetic in an air cooled motorcycle except in an emergency. The primary benefit of synthetic oil is maintaining viscosity over a wider range of temperatures. If there's an application where there is maximum benefit for the properties synthetic provides, this is it.

 

Why would you want to change to pure dino oil?
