In my Previa every 15k b/c I use Royal Purple and it has 9qt. capacity. (7qts in the pan and 2 in reservoir). ;D

drag car gets oil changes pretty often. 

old DD boosted car got oil changes every 3000ish km.

longest i ever went was 5000km on full synthetic, which included 8 track days, probably 35-40 passes

7500 or after a track day. roadcourse oil temps kill even synthetics pretty quick.

i use german castrol. AFAIK, it still tests as the best or near the best oil out there.

the newer modern oils generally can be left in the engine longer than the typical 3k mile.

OMG amazazing!!!!

I beat the piss out of mine, so it gets changed every 2500 or so. Synthetic in the Explorer gets it close to 4k, and the Trailblazer probably 5k+(whenever the dash tells me to lol)

what's currently the best? i know GC destroyed mobil1 in a 5k oil analysis done on a 3SG.

Conventional oil, 5 to 7ish k per change.  Slopped out D.   O0

I know its kind of old but here is the oil test I have DL to refer to. Oil%20Tests (http://www.scribd.com/doc/2428355/Oil20Tests#keyhptl03l8j76rsx1kgts)

And just found this of interest: http://www.carbibles.com/engineoil_bible.html (http://www.carbibles.com/engineoil_bible.html)

If you are using the right oil filter you can change your less often.  ;D

So if you can keep sand out of the oil pump, you'll be ok with any oil.


Fancy oils might have super neat pressure characteristics, but don't they also make you discover new leaks in the engine?

When I get bored... 2k-10k... I look at it to see if its still gooid quite often though

When you have something that fails (Mobile 1), costs you money in valvetrain and find something that doesnt (RP)... Then find specifics showing how hard the bandwagon Mobile 1 is alkong with empirical data as to exactly how much better your new choice is (based on research).. Its win. The shit costing a bit more than Mobile 1 and deciding to change itmore often  and actually take care of the motor (Not ewxactly a 120K mile D16 or GSR) makes sense...  Sand i n it or not.


Dumbfuck.

Oil I always use is Total. It used to be Elf but was merged. Doesn't get nearly as hot and looks great even after heavy use

Other good oil to look at is Fuchs.

Fuck emissions.

Get oil with zinc and phosphorous.

What are Rotella T's zinc levels vs RP?

No one uses Mobil 1

It appears from my little bit of research that new cams have not been tempered, they're still made like they were years ago.  Reusing an old cam with new oil seems to be ok with flat tappets since old oil had high zinc and this tempered them in a way.  Now only certain diesel oils and racing oils still have the high zinc.  So break new cams in with high zinc oil and then you can theoretically do whatever.


synthetics suck

Here we go with the mobil1 bashing again. Sigh. Seriously you guys do realize there are different blends for different weight oils correct? With that being said, PORSCHE recommends Mobil1 0w-40 in all their cars. Take into account, the minimum replacement price for most of these engines is $15k. Do you seriously think the company what has tthe best reliability ratings out of ANYONE on the planet right now, does so with crap oil in their warranty-guaranteed engines? I have replaced ONE engine in seven years due to oil failure, as it turned out the lady thought she only had to change the oild every 25k lol, and that engine made it to 50k before spinning the int. Shaft out the block. BDVT, you have experienced a catastrophic engine failure at the hands of mobil1, and that sucks. But there are several thousand 600+whp 911 turbos out there who have never experienced problems, and run 0w-40, which for the record I run in all my cars, and have for the last 6 years. I would agree that most the other blends are gov mandated detergent crap, as is most everything. Most synthetics are manufactured to the SAME specs (its called base stock, google if you don't believe) with the important stuff added later, like phosphorous, zinc, etc. How much of the good stuff depends on how they want to sell it.

Personally, owning nothing but turbo cars and driving a total of maybe 15 miles a day, I change my oil every 2k miles. Reason= contamination. Extra fuel from the warm up phase, and moisture build up from never getting the car warm enough long enough to vaporize it being the key reasons here. I also use bg107, which is basically a can of more o the same additives used to bring the oil to spec in the first place.

Is the valvetrain in a Porsche the same as DOHC VTAK Hondurs?

No, they aren't. Its an inferior design to the honda, since the cam lobes themselves don't have designated oil supply from oil bleeding off the rockers. They rely on splash from the oil returns in the head, despite the dry sump.

I recogzine the fact that spiker's engine isn't typical, and he is welcome to his opinion as I am mine. I'm simply stating a perspective, not throwing in lab results.

Twas an honest question with no other motive than to explore the differences between the engines.

So they do no use a roller follower?

I wonder.. are OEM Porsche valvetrain parts perhaps hardened for use with modern lower zinc oils?

Diesel oils... million mile engines with slopped out clearances and heavy reciprocating masses, ignition system?  Detonation.  Skeet in your mini wheats.

None. But Its not a terribly unique situation and pics arent hard to come by. Exhaust rocklers (esp VTAK) were HAMMERED with Troughs worn into them BAD on the VTEC lobed... Cams themseloves were fucked too, but the rockers were the most visibly impacted component. 

Intakes were a lil messed uup, but nowhere NEAR like the EX.
