Let the Coal Roll!
Ohhhh crap, another oil thread. Well, I am bored.
Older engines, I am not a fan of running overly thick oil due to start-up wear and also parasitic drag I prefer 5w30 or 5w40 for older motors. Heck if I could get 0w30 or 0w40 but that gets into high end synthetics which would be fine if it weren't for oil contamination shortening OCI.
I am considering fancy synthetics vs. more economical dyno because of the need for changing oil more frequently for old engines. Considering that carbureted engines pollute the oil quickly and most hot rods dont get driven much, condensation contamination is an issue too. Ive been considering not running synthetic in old engines because of the frequency of drain interval required to maintain non polluted oil.
Ive been running shell rotella T 10w30 for a while in my small (mowers and similar) engines, usually I will put a teaspoon of lucas zddp (looking for another brand currently).
I dont have any info on zddp content of the T 10w30 but I figure it is around 800 - 1000. I cant find if it is a CI type oil or a passenger car oil. I see some docs available but not sure if they are current.
That 10w30 rotella T can be purchased for less than 5 bucks a quart on amazon if you buy the 3 gallon pack.
Anyways, does anyone have any independent tests of the T 10w30 or current specs regarding ratings and zddp ppm?
Not really interested in 15w40 because of the undesirable start-up wear issues but discussions of any and all oil hypotheoretical meanderings are welcome.
Why is rotella cheap?
