Valvoline VR1 Racing Motor Oil SAE 10W-30

from British Bikes

I use nothing else in my 76 Triumph Bonneville, as it shares engine and primary oil. My bike requires Zinc oil and it works great, as my wet clutch gets gummed up. With regular oils I have a hard time freeing them. With this oil I pull in the clutch lever and kick through one time, next kick fire...

from Matthew

Adds extra protection for the needs of older engines.

We have been using Valvoline VR1 for 15 years now and have to say it has never let us down. We have had motors that have run 40 or more shows on this oil and the bearings look almost brand new. We recommend this oil to every racer that comes in the store.

Been using VR1 in old flat tappet engines for years and it's never let me down because it has EVERYTHING these engines need. I currently use it in my 74 F100 with a 360 FE.

from Randall

This is the best deal for zinc/phosphorus oil for flat tappet engines I've found. No additive needed.
