That recommendation is for the prevention of other wear issues.. The extended drain intervals are proving to take their toll on the hydraulic lifters ad vario cam chain tensioner pads and drive chains in the earlier engines.

Out of the last 6 engines I have torn down or repaired internally we have found no less than 16 "stuck" lifters, one engine had 20, another with 22 of 24 stuck and this is directly related to the insane extended oil drain intervals.

More frequent oil services reduce the fuel and coolant intrusion that the oil sees and that coupled to purging other contaminants that the oil filter may not collect is the primary reason for our oil services being carried out at no more than 5,000 miles.

The stock hydraulic lifters in these engines are like miniature filters, with very small passages inside them that collect crap before any other part of the engine... Stuck lifters can lead to reduced valve lift by over 10% per valve, thats why a recent service of the valve train netted a 16HP gain in the same engine after using our updated lifters... That engine had 22 of 24 lifters stuck and was the weakest 3.4 thats ever been on my dyno, after the service it was right back where all the others like it have been.

Jake, I went over to flat6innovations.com but a lot of the Featured Articles go to blank pages. Got a link to some sort of white paper or recommendations for oil issues (viscosity, type, intervals) on M96 engines?

Our development has taken ALL of my time for the past 6 months, so lots of tech articles are not finished.

The oil recommendations are something you'll never see from me on line. It is a VERY sore subject with me. Nothing I have experienced first hand parallels Porsches recommendations so to save us all the argument I'll plead the fifth..

EVERY time I make a recommendation people throw advertisements and "papers" in the mix that have ZERO empirical data from these engines behind them.. Its too controversial for me to waste my time engaging in these debates.

I think people are not looking for you to make a reco but rather state your opinion and why since it's never been heard. That's all.

I don't understand why you won't comment on what oil you recommend. I have never known anyone on this board to attack someone for simply stating their opinion on the subject.

The topic is simply too controversial and my recommendations do not parallel those of the manufacturer of the engine.

This topic has caused us lots of grief and too many debates. I am way too intense to have conversations on this topic without a chance of loosing my tact and professionalism...

The other reason why the topic is such a sore spot with us is due to the fact that the oils are CONSTANTLY changing their formulations without any advance notice and that impacts the effectiveness of the oil.

An oil that I once thought very highly of showed me a serious weakness this past weekend in my 996 at the track for a DE... It was the first time I had gathered this particular data and now this oil is no longer respected for the M96.

So as soon as I did make a recommendation it would probably change or I'd make a discovery that wasn't positive.

Sorry guys..

Wow. Sorry it's a sore spot.

Anyway, your associate Charles Navarro wrote this, which is pretty helpful: http://www.lnengineering.com/oil.html/name#m96

Yes Charles wrote that and with some of my input.. But those are his thoughts, not mine.

Mobil 1 is not the oil I was referring to earlier in this thread.

I tried it again last week and it pissed me off in one 83 mile trip. I drained it.
More on that some other time..
