Synthetic oils
I'm in the middle of rebuilding a '98 360 magnum. Talk about engine sludge when I first dug in there... ICK! It got me to thinking... what full synthetics do you guys like for your engines? Also what weight would you go with if not factory spec weight?
I've tried mobile 1, valvoline, kendall...
Out of the 'off the shelf' oils, Kendall was the best when it came to thermal breakdown/viscosity, and to me [besides the basics of oil/'zinc'] that is very important.
However, I only use the kendall oil if I run out of Schaeffers semi syn 7000
Schaeffers oil is the bomb/best IMHO.
I run a 340 and a 410, rev'em 6500rpm 'more for the 340' and cruise the freeways @ 35-3800 rpm on average, I change the oil the recommended' by schaeffer' 7k...yep saves money too=less frequent changes, this oil does not break down and turn into carbon soup like most others do in the short amount of time-3k like the off the shelf does.
I buy cases of this stuff, and if some of you guys around here would give it a try....you'd be hooked, the engine runs cooler 'no bullshit' and the psi stays up even after being wrung out on the hyw turning a constant 4k or so.
All my motors are clean, no burnt crust/coating, no sludge...perfectly clean.
20/50w is what I use in my 'built' engines.
I run 5/30w in our milage mizer compact.
