Been running the Rotella 15 / 40 for yrs in my 500 Caddy powered 40 Ford p/u with after market goodies. It was the only oil that would hold up it's viscosity in the 30 + summer heat!
X2 for Rotella 15-40. I used to run Royal Purple but I don't think you get any value running high end synthetics in carbureted cars. With Rotella you get the zinc protection and can afford to change it regularly. If i were running some crazy lift cam with silly strong valve spings I may go with Brad Pen or Royal Purple but for a warmed over street engine I think Rotella is the ticket.
I put the Rotella T6 in everything, it also has the JASO MA/MA2 ratting so it is good for wet clutch motorcycles.
I found Walmart is the cheapest place to buy it.

Isn't the T6 a synthetic oil? I've always thought synthetic wasn't good for older engines. Now I'm confused more than I was. TSC
So now I wonder if there are different Rotella T oils because that one says it is a diesel oil ? Boy, things I once thought were so simple. Thank you Toomuchjunk and 123pugsy. I will really have to look at what is on the shelves next time I am at the store to sort this out.
