Syn oil
Put the Valvoline Blue Syn 5w40 in my truck for the 1st time this oil change & I have to say I'm pretty impressed.
No leaks or any downside that I can see as of about 1000 miles & truck started in 25 deg temp like it was 75 deg. Pretty good for a truck that would always romp a little at anything around 40 deg.
I'll probably run this stuff year round from now on
