castrol 10w30 - when in Japan I was told - Do not put Mobil 1 in our cars - it could damage the seals- never put it in the fd.

I dont understand why. If you're already down there, does it just help to just change the filter too?? I mean sure its more money but how much are filters these days? 5 bucks? lol Idk, maybe it doesnt make a difference but i just like to complete the "oil change job" by replacing all the necessities. |

My friend with a turbo integra does the same exact thing. Change filter each 2 oil changes.

What does a porsche engine have to do with our cars? (Hint: the answer is very close to nothing) Dave |
royal purple 20-50

Wesson or Crisco Pure Canola oil mixed with Marvel Mystery Oil...you simply can't beat it.
And your car smells like French fries. |
Shell 10-40 non synthetic and change every 600m miles ( 1000km ) with filter change as well....

Just thought this might be appropriate to the thread. |
Remember that the reason the anti-wear additives were reduced was to prevent fouling and disabling the catalytic converter(s)...
So if you do still have a cat, and run a "racing" oil, be aware that it may shorten the cat's life. |
Dave,
While that's a factor, are we sure that's completely true with the higher exhaust temps we see? And that's a question, not an argument. |

Zinc and phosphorus (the two components within ZDDP that are deemed poisonous to cats) are basically minerals, so the high exhaust temps of a rotary won't make any difference. They're still going to deposit on the cat substrate regardless.

Molbil 1 filter and Royal Purple 15w30 at 2000 miles.
Turbos and synthetic oil go together Injected with Mercury "Quick Silver" Premium Plus 2-cycle outboard oil. |
RP 20/50 - Probably will convert back to Castrol 20/50 before too long.
