Oil Question

[buddyten]

I know this topic has been on here a lot, but I am just looking for some clarification.   I am not "versed" in ash percentages, etc and just need to know in the simplest terms about some oil

We have 89 Eagle 6V92T w/allison tranny.    The engine was completely rebuilt just right before we bought it.   All new Detroit parts, done by Detroit dealer.  Has about 20K or so on new rebuild.    We have been using Delo 400 Straight 40W.

It is getting increasingly harder to find the Delo 400.  I usually have to order it through O'Reillys (that is what we used on our old bus).  However, they have another user (a logging business) that uses Delo 100 Straight 40, and they keep several cases in stock for him.

Just would like your opinions.

Hi buddy, I hope luvrbus chimes in, I have heard  DELO 100 & 400 is good as long as its the 40W, multi vicosity went right thru my 8V71 like a sieve. Depending on what region your in, O'Rielys might be the only way to get Delo, for a while all I could get was ConocoPhillips 76 in 40W, then they changed and the ash level was over 1.2, lvmci...

Delo 100 works use it most have gone to the 400 40w because the 100 40W is hard to find all C rated oil have 1% or less ash nowadays the EPA took that worry away for you The oil of choice for a 2 stroke is Mobil Delvac 1240 IMO

Buddy -

Mobile Delvac 1240

Shell Rotella T

Chevron Delo 100

These are the three most popular correct oils to use in your 2-stroke Detroit.

Of the three, the Delo 100 has the lowest sulfated ash content, at least it did the last time I looked at their MSDS sheets.  Detroit's specs called for less than 1%, Delo 100 was at 0.85% and Rotella T was right at 1%.  Clifford says the EPA made them all less than 1% now, so who knows. . .

Chevron's own website states that Delo 400 is NOT acceptable for use in the 2-stroke.

Since you often order from O'Reilly's, their P/N for the Delo 100 is CHV 100-40-1.  If the teenager behind the computer struggles with that, tell him to put CHV in the Vendor box, then the rest of the number in the regular P/N box.

Most importantly, do NOT use multi-weight oil in this engine!

FWIW & HTH. . .

Guys read the label on the jug for the Delo 400-40w it will list 2 series of the MTU engines read the jug for 15/40 delo 400 one goes away guess which one the 2 strokes.  Wrap your head around this the 60 series calls for 15/40 only and 1% or less ash it has always been 1% or less ash on any engine Detroit ever built even the 100,300 and 500 series engines which were a re badge engine to much is made about the ash deal it's not there anymore like the Delo 400-15/40 has .05 ash there are approved SL rated oil for a 2 stroke also.I came from the old school before the Delo 100 was ever marketed for a 2 stroke plain old Delo Rpm,Gulflube,Delvac,Texaco or Esso where the brands

All of the above are the latest Specification sheets from the mentioned manufacturers that I could find within a few minutes of Googling.  If you read them carefully, especially the Applications and the Sulfated Ash percentages, you'll see that Clifford really is the <snark> expert. . . 

FWIW & HTH. . .

Hi Clifford and RJ, do you have to go all the way to Norway to get DELVAC?, cant get it in LV, lvmci...

[luvrbus]

It is Power Guard at WW Williams when they run their annual sale it is around 10 bucks a gal funny how oil is regional in Texas on the coast one can buy  Delvac 1240 at drugstores and BBQ places   

[Combo]

 you guys are great, everything we need to know about oil, all in one post! I'm going to print out the spec sheets and keep them.

Thanks guys!

LOl read the SL rating on the 400 then read your DD bible funny they post different stuff on the net than they do the jugs no mention of MTU but the jug has it now the 400 15/40 is only made in LE .05 ash like racing run what you bring 

Don and Geoff are like me to much BS about the oil both run 15/40 in their 92 series one uses a synthetic 15/40 hell of a marketing deal  . I just pulled my DD bible for a 60 series 15/40 recommended ash content .50 long ways from 1.00 + Chevron is saying

 Then fwiw 40w with the CF rating is for closed crank case systems in the marine engines I never knew that I always thought it was 15/40 only for a 60 series so now I know why you can use 40W in a series 60 check out the CJ-4 rating and see what the ash content is

We used a higher ash content oil sometimes in the 2 strokes to balance the TBA it's all in the DD bible

[Geoff]

I'm not really worried about the ash content as much as I don't like the way 15w-40 breaks down and turns into 15w-30 in 50 hours or 3k miles of driving.  I ran oil analysis on 15w-40 Rotella to see how it breaks down and you have to have a tight engine to run 30wt or have a oily mess from thinner oil.  And it only gets worse after 3k miles.

The only 40wt I can get easily from my oil distributor is T5X HD 40wt.  Now he tells me he has T3X 40wt. left over from a barrel.  So I guess I go buy a few pails of that.

None of this stuff makes sense people are always looking for CF-2 rated oil that is a obsolete API rating and has been for several years and oil companies are still using the CF-2 rating to sell oil 

[RJ Long]

Buddy -

WTF, just buy whatever oil you want and throw it in your engine, it doesn't care.

Only your wallet will know the difference, somewhere down the road.

 

[oldmansax]

FWIW, Castrol makes a 40W with the less than 1% ash rating. It's available in lots of places around here because we still have a lot of marine use.
