Alright, here it goes. I read the "Uberpost" and realize that 5W-40 oil is recommended (Lotus Elise), but when I search the net, I'm seeing that some 5W-40 is diesel engine oil.

Same thing or different?

What brand of oil are you "DIY" putting into your cars?

Ignore the diesel reference as being inappropriate. The extra zinc constituent of diesel oil is a positive for the configuration of the engine in our cars. All the other specifications of this oil are suitable.

Rotella T6

Shell Rotella T6!
I see the specs on the Shell Rotella T6 are not the same as the Mobile 1 or Castrol Syntec (now called Edge) - both match the spec requirements in the owner's manual.

Red line 10w 40 has the zddp you need. Ryal purple good as well or the motul. There are many differing views. I alao use 6 oz of redline breakin oil at each change. It is basically straight zddp

lots of options out there for good oils with ZDDP-if you google ZDDP oil you'll see lots and lots of various forums discussing it-this additive is important in all sorts of high performance engines so there is a constant hunt for the best.

5w-40 is just the weight you need-but these motors really need a good dose of ZDDP-mobil 1 turbo diesel truck, shell rotella T diesel truck, and some of the royal purple and red line oils all offer it.

Looking at some race/high performance engine forums, many are wary of zddp additives after the fact, because you are not getting a consistent amount of ZDDP in your oil pan from oil change to oil change, unless you are hyper precise with both oil and the additive.
