Understood the Mobil Vtwin is intended for air/oil cooled use. But the one thought I had, is there any downside to the dual usage it provides- it also serves the motorcycle transmission and wet clutch?

All types meaning off the shelf any brand Detergent.

I would run the engine, set up a baseline tune then drain the oil. About 2 hrs of run time in total. Then Delo or Brad Penn...I'll discuss Henry's Brad Penn finding with him as I have not heard about it.

The only critical area for oil I have seen is the Cams/rockers. The majority of issues been reground rocker arms that are not parallel.

Thank you!

This question usually gets the same type responses that all oil related questions get - some say "yes" and some say "no". Based on my personal experiences with using motorcycle oil in non-wet clutch engines (Ducati 748R which I endurance raced for three season and my 930 - both engines which I overhauled at one point), the answer is no, there is no downside. Obviously, mine is a very limited experience base, however.

Kevin,

My understanding is that the V-twin Mobil 1 lacks the friction modifiers present in the normal Mobil 1 for cars. So, without the modifiers, I guess you could expect a slight degradation in fuel economy. The normal Mobil 1 in the 15W50 viscosity still has the elevated ZDDP that our flat tappet motors need. Or, if you go to Mobil 1 Racing oil, all the viscosities have the elevated ZDDP levels.

Regualr Mobil 1 15 /50 has 1350 ppm Zinc
V-twin has 1750 ppm Zinc
Brad Penn has between 1200- 1500 http://www.penngrade1.com/Zinc.aspx

Flat tappet engines need 1400-1500 ppm zinc

Chris,

You are generally accurate on your comments on zinc. What needs to be added is that most oil suppliers have cut the ZDDP levels from 1300-1500 ppm to levels around 650 - 750 which appears to be unsatisfactory for our flat tappet motors.

If you are in the market for 15/50 oil, then I question that the Mobil 1 formulation isn't a good choice, even though it does not quite meet your criteria of 1400 ppm for zinc.

In reality, whether you run Mobil 1, Mobil V-twin, Motul, Joe Gibbs, Total or some other brands I may have left out, it will come down to availability and cost. All these oils are expensive and may not be readily available. And, all thanks to the USEPA for creating this dilemma for people with older cars.

Thanks for the tips on the V-twin formulation. Sorry for the sidetrack but I thought i'd ask since the mention of it came up.

I'm going with the Chevron Delo 400 for my motor when it's done. If it's good enough for Henry, good enough for me! Already got two boxes (6 gallons) on hand from Costco!!!

Thanks for the tips guys. Just got six 1 gallon Delo 400 30w jugs from Amazon. Let the engine break in begin.

And that is precisely what we see here. Adding ZDDPlus SIGNIFICANTLY REDUCED this oil’s wear prevention capability. Just the opposite of what was promised. Buyer beware.

The Mobil 1 V twin stuff is $14/ qt expensive. I usually mail order it through Amazon. Some times it goes on sale locally.

A real V-twin has the transmission and clutch separate from the engine (attached by a fat belt). I question if the Mobil V-twin oil is designed for a wet clutch environment.

This could quickly morph into another 50 page oil thread, so let's keep this topic to "break-in lubes".

GM's EOS additive (now marketed as AC Delco Assembly Lube) is widely used on engines, for break-in as well as long term. Here's some discussion about it:
E.O.S (Engine Oil Supplement) | Oil Additives | Bob Is The Oil Guy

Sherwood

So should one conclude from post 50 that the Lucas 30wt is the best oil for break-in due to the very high concentrations of ZN, Ph and ZDDP?

Just curious where you got all the data from post #50? Also how was it determined?

What about this stuff?

I believe Porsche,AMG,Corvette and etc use Mobil 1 from the get go. I have disassembled quite a few air cooled 911 engines and have yet found any tappets (my MG has 8 my 6 has 0). The 20 min cam break in? The main reason is flat tappet engines need the oil splash from the crankshaft to lube the cam.

True, our P engines do not have tapperts or lifters in the traditional sense. But, the rocker arms are lifted directly by the cams, so there still is the same sliding kind of motion that there is in an OHV engine with flat bottom lifters. If you contrast that with, say, the valve train of an LS engine with its roller lifters, you cam see why people desribe a Porsche six as a "flat tappet" engine.

break in oil.
 

Hi,I have always used Valvoline non-detergent straight 30W for the first 500 miles.Then do your leakdown te full st to determine ring seatage.No full throttle at first 500 miles.

Henry, My mechanic used Valvoline VR-1 20/50 for break in. Was told to change after 1,000 miles. Have not put any miles on new rebuilt yet, only been starting for 30 min at a time while I do my brake upgrade and bushings replacement. Was told it would be fine to stay with the VR-1 20/50, but should I go to the Delo 400 SAE30 after the 1,000 miles?
