engine oil?

What's the current choice? I was using Swepco 306 20/50, last year I switched to Mobil 1 v-twin 20/50.

The Mobil 1 v-twin should be good. Don't know much about the Swepco 306. Amsoil is also reported to be very good, at $12.00/quart?

i called mobil 1 about the V twin oil. they said NOT to use it in my car.

synthectic is the top requirement.

amsoil
mobil 1

my brother always ran amsoil. he also had it analyzed at each oil change. it always came back good.

Synthetic v-twin is what I’ve been running. I thought it had a higher zinc than Swepco 306.

That's what I have used for past 8-yrs. Engine runs noticeably cooler and don't use any oil between oil changes... Still very very clean at 3K miles. And, no smoke on start-up.

I always understood it had a fair amount of ZDDP. As I look, I can see the Amsoil version does, too.

I want to say something with detergents?

do me/us a favor, call them again and see if you can get more info. the guy I talked to was not very talkative.

I did put it in but went and bought some stuff that made up for what it was missing.
I will probably just go back to mobil1 unless I get off my A$$ and order amsoil

The guy you talked to at Mobil 1 probably has no actual knowledge or work experience with engines... especially older 911 engines with two large valves held shut with relatively stout valve springs so valve float is not an issue under ~7200rpms, and he probably had no clue about ZDDP, oil shear, and flat tappets riding directly on the cam lobes.

Mobil markets that oil for Motorcycles that have no catalytic converter that will be ruined by ZDDP zinc and phosphorous deposits so when you call.. they are not gonna say yeah it might be better for your cams and rockers, give it a shot.



Amsoil is really good oil too.

As long as you don't have a catalytic converterter it will work fine.
Two valve per cylinder 911 engines are air cooled with local hot spots just like the 2 valve per cylinder air cooled V twin motorcycles Mobil 1 V twin synthetic 20w 50 is made for.
Both engines use oil with detergent that helps to keep oil carbon dirt in suspension so it doesn't settle and turn into oil sludge as long as you change the oil and filter every 2 to 3 thousand miles.

Years ago there was a really long thread about engine oils and ZDDP levels in the engine forum. It could take a few hours to read through it all.
If you havn't read it you might like it. You'll learn something from Charles Navarro.

Like all large busines's, incoming phone calls are recorded and sometimes someone may listen to them later.
The guy answered you with a generic answer to protect his job.
Mobil markets their Mobil 1 automotive oil for automotive use so thats what Mobil oil employees are going to tell you to use if you call them.

he did tell me after a certain point no more ZDDP really does not do any good.
I think I have heard that before.

look, don't take my word for it. I just think there is caution with the Vtwin and not having the same additives as auto motor oil.
if anyone really wants to use and has concerns, then do the research. also ask about hi ZDDP levels.
you guys can believe people on here that are DEFINATELY not engineers for any oil company or as I said, contact the oil companies if you really want to know about oil.
I am just saying there could be concerns about using Vtwin in a car.

I had already put it in at this point but I dot think I will use it again.

For what its worth, if you look on the Mobil 1 website, you will find that their 0W-30 and 0W-50 Racing oils both have 1750 PPM of Phosphorous and 1850 PPM of Zinc, the highest of all their oils. The V-Twin oil is next in line at 1650 and 1750 respectively. I think that this would be a very good choice for Porsche air-cooled engines, especially in hot climates, where a 20W-50 oil is recommended. Just my 2 cents.

IMO, either of these two (in the links below) are a no-brainer compared to other oils out there, not saying the other oils are good/bad. Been using these for 105K miles, with a total of 140K miles on the engine.

If you have questions, call them and ask, that's what I did 12 years ago when I was shopping oils for this car, then I stopped worrying, change the oil every 5K, and just drive it. The oil analysis always came back continue to use after 5K, but I still changed it.

V-Twin oil is for a motorcycle with a wet clutch, as is any motorcycle oil. Using automotive synthetic oil in a wet clutch engine impregnates the friction discs of the fiber plates in the clutch rendering it useless. Ask me how I know? I'm a motorcycle dealer and have replaced many clutches from people using auto in the motorcycle. Different type of lubricating qualities. I use Amsoil or Mobil 1 in my 930, no problems.

Yes! Thank you. You don’t want those motorcycle wet clutch friction modifiers sloshing around your 930 motor. Mobil 1 15W50 full synthetic. It was made for us:

“Mobil 1 15W-50 is formulated with SuperSyn, an extra high-viscosity synthetic fluid, plus extra anti-wear additive to provide extra protection for severe service applications. Mobil 1 15W-50 is recommended for high performance vehicles including turbocharged and supercharged engines where a thicker oil film is desired. Mobil 1 15W-50 is also recommended for older valve train designs that may benefit from a higher level of anti-wear normally not required for newer generation vehicles. Mobil 1 15W-50 will also provide better anti-wear protection for higher valve spring tensions in certain racing engines.”

^^^ Exactly why don't you want those friction modifiers sloshing around?
Those oils are designed to be used in wet clutch and non wet clutch engines.
If there was an issue the manufacturers would specify two different oils and the oil manufacturers would make two different oils.
But they don't.

Have been using the Mobil 1 15w50, as well. (Not the V-twin 20w50.)

Before that it was the Valvoline VR-1 or Brad Penn 20w50.
