- Valvoline VR1 20/50 Racing Oil
In April of 2019 I switched to Valvoline VR1 20/50 Racing Oil due to the higher zinc levels over the Shell Rotella T4. It's also the recommended oil of RPi Engineering, a Rover V8 Engine Specialist in the UK. Previously I was using Shell Rotella T4 Triple Protection 15W-40 Heavy Duty Diesel Engine Oil. I began using Shell Rotella T4 Triple Protection 15W-40 Heavy Duty Diesel Engine Oil around April 2013 when it was known simply as Shell Rotella T 15W-40. My RRC had about 200,000 miles on it when I switched. I had been using various Castrol grades previously. With regular oil changes at aproximately 3,000 mile intervals my engine still runs very strong. Which with the over 260,000 miles on it running the stock 3.54 gears and 33" tires, is certainly impressive for a 28 year old Land Rover V8.
