Bought Valvoline VR1 20-50 - ZR-1 Net Registry Forums

mmkkpro · 4 Weeks Ago

I bought Valvoline VR1 20-50, apparently I wasn't paying attention. My 1990 ZR-1 #2822 has 88k miles right now and is running great. My question is, am I safe with this weight oil? I live on the SE coast of NC and it's hot down here. If anyone has an opinion on this weight oil in the LT5 please chime in. I have been running VR1 10-30 Dino oil with no issues and a Bosh 3401 filter. I can save this 50 weight for my 1972 455HO Pontiac if need be. Thanks guys, lovin my Z, over 10k miles since May of 2020.
