I know the most important thing is keeping a good oil level, but want to see what the concensous on oil brands are. I have been running semi synthetic castrol.
Whatever is on sale. It’s all the same
I’ve always used Mobil 1 more out of habit than anything. I won’t tell you it’s any better than the other major brands. Some of the house brands are probably just as good as well.
Pennziol Full Synthetic Platinum has natural gas as its base component. It’s considered ‘cleaner’ than crude based like Mobil One. Strictly a brand preference if you do 5K changes. Semi synthetics can contain a little as 10% synthetic and be called that.
Makes me wonder if I would notice any difference switching from semi castrol 5w-30 to that pennzoil ive seen so much of. Granted its an s10 I would be throwing that nice oil into. But its a low miles one.
My engine has been very happy with Pennzoil Platinum. I burn less than a quart beween oil changes.
