My excuses to the OP but I personnaly think that BS about oil is getting rediculous ,and agree with Rob that it migth steer peoples specially new guys coming on the forum in the wrong direction, my present car is the seventh Porsche that I've own since the 70s they were all kept alive without any mechanical issues by changing oil & filter every 5000k miles maximum the sixe one is still going strong after 27 years (never open up the motor on that one neither) oil use was 20W50 exclusively & planing to do the same with my 968.We can stand here & debate brand vs brand _viscosity vs viscosity but it all come down to one thing, if the oil you choose to run in your car years after years does the job stick with it.And to finish it off will like OD to realize one thing ,do you know how many time over a period of 27 years my 944 was started in warm & cold weather with 20w50 in it ? answer hundred of time yet like I said it still going strong with no mechanical issues.
There are many factors much more important than brand and flavour of oil.

obviously a trade-off.
but, with oil failure at high rpm (not summer temperatures) being the worse of two evils,
you all have convinced me to keep running the molasses that flows like crap at startup.
this post by Hacker was considerable, cuz he's got over 1 million posts on Rennlist and knows a thing or two (even more than some of you all, maybe) about Porsches.

.... No way I will ever run an oil with that wide of a viscosity spread in a car I care about.
At least not again. My 100% street driven 944S puked up a rod bearing on Castrol 5w-50.
No thank you

Most of us do not drive our cars when it's cold outside.
You also need to define "cold" which is not 40 degrees when it comes to modern engine oils.
As other people have suggested, you need to talk to experienced engine builders and mechanics who have seen the damage from using the wrong oil in these cars.
Post all the links you want about oil theory, doesn't mean squat to those of us that have seen results in real life.

I guess the point is that if you're looking for the very best possible oil, to eke out that last fraction of a percent of performance, everybody's always going to give you a different answer...but for normal street and track use, as long as you use any decent oil, change it every 3000-5000 miles, and don't rev the **** out of it until it's warmed up, you'll be fine.

sorry for selling the "thinner is better" snake oil.
maybe leave the "thicker is better" idea to chasing hurricane surf in Rhode Island.
goes "epic" @ 1:20...

My shop uses 1qt Redline w/ZDDP and then fills it using Mobile 1. The ZDDP puts good additives back in the oil now missing from "street legal" oil. Also agree with JDS998...change your oil at the recommended intervals and you will be fine. Oil is the lifeblood of your engine....keeps it clean and lubricated.

Oil is like religion, politics, etc. Argue all you want, nobody's changing their mind.
So is that why you've racked up 5000 posts in 1 year? Trying to catch up with Hacker, Juan, and V2?
Post count means NOTHING for credibility. It only shows how many times someone has posted an opinion. Credibility comes with the quality of posts, not the quantity.

ran the car VERY hard today from ____ towards Chicago.
me and a beemer tore it up. 85-115 MPH. all day.
almost wished i hadn't changed to the 0w-40 winter oil until next week.

So I guess it does not matter in the end what I use for oil in my no torque inline - six Odurandina? You should feel how much torque this engine does not have at 7500 rpm shifting from 2nd to 3rd

i love inline 6 ingines. TONS OF TORQUE, and TONS of power at low rpms make them great touring car engines for sure.
GOD, what an awsome car a 968 would be had they consigned an engine like that for the cars.
what is the displacement of that engine ? 3.4 litres ?
the old slant 6 chrysler engines would do fine in most of today's SUVs. (might be some issues with emissions).
they made that cummins 6 for the Jeeps. and you can buy the crate motors...
at one point, i had the car up around 4,700~5,000 rpm for like, maybe 7-8 minutes in top gear.
oil pressure was showing @ about 5 on the guage.
i just wished i was running the thicker, summer synthetic. you can push the engines with confidence running that summer oil.
i'm trying to make it a point of not driving like that the winter months. my bad.

Yes Raj, (I am Fred), 1992 E34 M5 6 speed with the matching 3.23 diff. I was thinking at one point to use this model of TB's for the 968 turbo but there is just not enough room with a turbo to get 11-13 inches of runner before the plenum.
968 turbo (4.5 year project) I was waiting till I finished to post but there are some forums members here that (Patrick) that do not realize the changes I made as a result of just talking with them. Was waiting to say that when I finsihed. I have Raj to thank for the splitter
Other shots of the E34 - 197,000+ miles and she still will rev to 8000 rpm in every gear (but sixth - never tried it)
