You guys get played like drum when it comes to the ash in the engine oil none of the stuff can have more than 1% ash content check out the lasted and greatest oil from Chevron the Delo 400 LE  1 % ash in the 15/40

good luck

I hear you on the ash content, it's been like that for a while now.  Where I get my "I don't understand" look on is the viscosity stability of the various modern 15W40 diesel oils in a two-stroke piston/ring heat environment and what that may do to the rings.  With my "I don't have a clue so I'm gonna guess" hat on, I bet the modern synthetics are just fine,  and if you change them regularly the dino oils are too, unless you are running max power/max load for hours on end.  But I have no idea how to find engineering (as opposed to anecdotal) proof  of that.

In my race cars,  when I was running very high compression, high output engines in the old original Mini Coopers, which had about the orneriest oil destruction system I've ever encountered (the gearbox and differential shared the same sump, hence same oil, as the engine) I would see a distinct drop in oil pressure at hot idle after about 10 hours, and that was the viscosity of the oil going down to the 20 number  instead of the 50 weight of the multigrade split.

Although there are many that say a good multi-weight will work just fine, as long as I can get the original stuff I will continue to use it.  I recently got Delo 100, 40wt through O'Reilly's.  I do not remember the exact price but think it was in the range of $13/gallon.  Their part number is 100-40-1.

Clifford, I already did.  If that company would give me their oil free, I would go for it too.

All the years I have known Cole he has never own a 2 stroke 71 series or 92 series that he did not use a synthetic oil and he never had a engine that would use 1 gal between oil changes and he wrote the book on DD 2 strokes lol

I also buy mine from a marine distributor in LA but they give me no price break that I can tell, I paid $13 a year ago and assume it has gone up a bunch since then.

Never even thought about O'Reilly, there is even a store in my small town!

Holy Moley Batman! I never expected to get as many responses to my question as I did.  Many thanks to all of you..there certainly is plenty of info to research.

The general consensus is that the Delo 40W is the way to go...but if it is strictly based on the ash content (and I suppose the non-foaming as well) the Aeroshell 40W minght be a place to look into...but hang onto your hat for the prices.

The best news today is that the price of crude oil is down (naturally, I filled the fuel tank just before I got home to NC @ $3.99 gal.) but since I own it now I guess I won't complain.

Again guys, thanks for the replies.

If it's in your tank it's an asset - it's only if it's gonna be in your tank that it's a cost...   Grin

Bob,
    Last time I purchased Rotella T in Arcadia, the girl said "I I have good news & bad news, The good news is that the price per case dropped, the bad news is that now there are only 3 gallons in a case instead of 6".  Jack

Jack,

That change happened two years ago as I remember and a funny thing happened to me the first time I bought the 3 gal cases. Shell said the change was so it would be easier to carry! Ha, sure it was! It was just a coincidence that the gal price went up a bunch at the same time.

The guy I bought the oil from i LA charged me the gallon price for a case! It was pretty funny so when I got home to AR I called him and told him to send me a bill for the remainder. He was so flabbergasted that he told me just to keep the oil at that bargain price.

Yup!  When I went to pick up my case of Delo 100, thye told me that they had 2 cases delivered.  I told them I would take one, so they handed me a 3 gallon case.  I therefore took both.
