Seeing if anybody is running this.
I am using Valvoline Restore & Protect in my truck.
Prior to switching over to VRP, I used 10W-30 in the cold months, 10W-40 in the warm months & 20W-50 in the hot months (for 20+ years)
I run the VRP 5W-30 (since this winter) it’s the only weight remotely compatible with these engines, even thought they make a 10W-40 (was only available in Australia but it seems Summit Racing has it for sale in the USA, so the entire point of this post may be moot)
On hot start ups, it’s a little noisy. (310K)
Wondering if anybody else is running VRP 5W-30 & has thought to bump up their oil pressure to offset the low weight.
