It's one of those which you want to do but won't feel much direct difference
, and IMO it's more appropriate for turbo cars which produce plenty of heat
and pressure. |

What motor oil is best for my aircooled Porsche?

"Can I use a diesel oil like Rotella to break in my engine?
Many cam manufacturers have recommended Rotella T in the past for cam break
in. Remember, this was the CI-4 Rotella T some manufacturers were
recommending, not the new CJ-4 Rotella. Be advised that we do not recommend
the continued use of the new CJ-4 Rotella T for cam break-in or any other CJ
-4 oil for this purpose. Additionally in support of this position, magazines
such as Fleet Equipment, in one such article "Focusing on Oi |

The more detergent an oil is, the more anti-wear additives are needed. That
means the correct amount of Zn and P in any given oil is a moving target.
More recently, in the development of the IIIG sequence, developers went so
far as to say that there was no need for the VD and VE sequences for testing
of OHV (overhead valve) engines because these engines are not commercially
available as new anymore and do not reflect the needs of more modern engines
. In a SAE paper titled "How Much ZDP is Eno |

Can I use a diesel motor oil in a car?
The newest CJ-4 formulations are now limited in the amounts of Zn and P
allowed, compared to the CI-4 formations most users are familiar with. If
the oil says CJ-4 or LE or "Low Emissions", even if it also lists CI-4 or
CI-4+, more than likely it conforms to the new, lower levels, and should be
avoided unless you have a 2007 and later diesel which requires these oils.
The verdict is still out in my opinion on the performance of a CJ-4 oi |

the 15W-40 Rotella T with Triple Protection. The answer:
"Shell Rotella T Multigrade Oil SAE 15W-40 with Triple Protection Technology

Hi,

It is a Group 4/5 lubricant
