Oil viscocity 5W50
I will use Vavoline VR-1 racing oil in my engine. 3" mains and 2.2" rods.
Bearing clerance .0030-.0032 mains and .0028 rods. Valvoline has this oil in 20W50 and 5W50. I dont really like how thick 20W50 gets in the spring and fall. Any reason not to run 5W50 instead? Sounds like a perfect compromise, but it has such a big viscocity spand that I get suspicious. |
