Ouch, i'm paying a hundred bucks a case for any flavor. It is good stuff, the only oil my engine builder will use along with Wix filters.Buying three cases of PennGrade hurts.. just did that. 10/30 for the Bee, 10/40 for the Dart and 20/50 for the Bird. $579 Canuck bucks for 36 quarts.
"Shell Rotella T is a line of heavy duty engine lubrication products produced by Royal Dutch Shell. The line includes engine oils, gear oils and coolants. The oil carries both the American Petroleum Institute (API) diesel "C" rating as well as the API gasoline engine "S" rating. Ratings differ based on the oil. Rotella oils like T3 15w-40 meets both the API CJ-4 and SM specifications, and may be used in both gasoline and diesel engines. However, it is formulated specifically for vehicles without catalytic converters, containing phosphorus levels beyond the 600-800ppm range.[1] Therefore, Rotella is not recommended for gasoline vehicles with catalytic converters due to the higher risk of damaging these emission controls.[citation needed][2] Newer formulations of Rotella T6 however are API SM rated as safe for pre-2011 gasoline vehicles."
Your absolutely right, however its today and not 1 year ago 5 years ago or 10 years ago. Some things people ran 5 years ago arent available today. And my build is a completely rebuild 440 60 over. I currently live in SoCal but plan on moving to a much colder climate in the near future, so what I run here amsoil Zrod 10w-30 with Wix filter gets me a steady 60psi at 200 miles. However at 100,000 miles when there is some wear on tolerances and pressure drops, it won't be sufficient anymore. However if I live in a colder weather area and I start to see higher pressures I will drop to a 5w-30 maybe. So just seeing what certain people run in differents areas with different mileages is nice to see. The brand is not what you should be shopping for. However if a brand is prone to breaking down in our older iron block engines faster, then it would be nice to know. The weight of the oil should be driven by pressures and the additives driven by what equipment is being used. So far my Zrod is working great, but its only been 200 miles on the rebuil so far. My flat tappet without catalytic converter should be getting high zinc and phosphorus additives and because SoCal in the beach areas is 60-80 almost year round 10w-30 with the new tighter tolerances is getting the pressure you need. My father would have shot me 5 years ago if I wasnt running penzoil conventional in my cars. Now adays if you are running that you either don't care, are uneducated in lubrication, or cheap.
Thank you, Dad. This topic has certainly been beaten to death on here - and is perfect for the OP
Thanks for your input
