I tried a fully synthetic and loads of oil leaks.
Used this "Dinosaur Oil" for years in a Porsche 924S and it is the best in my humble opinion.”
“I use Valvoline VR1 in three Jaguar classics a Jaguar C-Yype replica 3.4 litre, a mk2 3.8 litre saloon and my track car a 3.8 litre E-Type Jaguar. All cars are driven to their limits reularly and perform perfectly, I put some of this down to the suppurb VR1 oil”
