“I have been using this oil for many years in my high performance 6 cylinder 2.5l triumph engine. It was recommended by the engine specialist who built it”
“I have started using valvoline in my rover v8 engine and my classic ww2 jeeps because it has the high zinc content , old engines furr up inside the water chanels so the cooling becomes less effiecient over the years and extra heat causes oils to thin so I want to give my engines as much prtection as possible and have now gone over to the valvaline vr1”
“Great product. I use it every classic car engine. Gives the very best protection to older vehicle engine tolerance. And I find holds a higher oil pressure when engine is hot. I haven't found any other brand to do this. So yes valvoline 20w50 VR1 is the only choice.”
