Who makes Detroit diesel oil????

[Busnut83]

Just wondering what major company makes the oil sold by stewart stev,  as  15 40 detroit diesel???

[luvrbus]

Mobil Delvac is the manufacture of all oil sold by Detroit in their jugs has been since the beginning the Mobil 1300 is 15/40 and the new oil with no ash is the MX 15/40 good stuff.
The Delvac 1240 was for the 2 strokes the 1340 had 1.1 ash but it only has .05 now

I sell Exxon/Mobil products for a living so my recommendation is obvious. Mobil is the factory fill oil for Detroits.

Rotella by Shell makes the straight 40wt. I use in my 8V71 DD

[Busnut83]

Thanks...  The prevost 60 uses the Detroit oil and I was told not to change... My 6v92 I only use Rotella 40...

[belfert]

Why are they telling you not to change the brand of oil?  The Series 60 just uses 15W40 and it isn't as picky as the two strokes.

 about straight weight oil,  if any one else is  looking for 40 weight low ash oil for DD 2 stroke, in las vegas you can find it at the 76/conoco/phillips warehouse "rebel oil" @  Sahara Ave. & I15, or ww williams in NLV. I have not been able to locate any chevron delo 40 weight in LV without ordering it, lvmci...

Tom check Car Quest in LV, Boulder City Auto parts also carries the Delo straight 40wt on the shelf

This comes up every so often.

Here's my input. I know there are die hards that disagree. I probably have put more miles on my outfit than most. All of it towing a big trailer. Most of it up and down the Alcan and the Cassiar.

I use Chevron if available. My only real concern is that it states on the container "formulated for detroit engines" and that it is 40 wt. I will use a gallon of 30wt if needed during cold weather.

My engine has been on an oil analysis program since it was installed as a new Reliabilt remanufactured engine. The analysis shows the oil is OK with no adverse trends.

I am more concerned with what the container says the oil is for. If it says heavy equipment and farm equipment but does not state over the road trucks, I look for one that does.

Any distributor could order it for you.

Chevron 100 (40 weight cause it's hot here in Texas in summer) in my 8v92. Any oil distributor has or can get it. I buy mine in bulk and keep extra oil tank full above motor for top offs if needed. My bus only has 50 some odd thousand miles so it doesn't use a drop of oil.  They tell me it will or leak it. So far you can still see the silver paint on motor and no oil leaks.

Delo 100 seems to be the choice of oil on this board me I prefer the Mobil Delvac anyway I can avoid the Delo 100 I do JMW I don't care for Delo 100 or the Shell Rotella in a 2 stroke

good luck

[muldoonman]

Isn't the ash level what everybody is concerned about and  the Delo 100 the lowest?

[luvrbus]

The Delo 100 was originally developed for the 149 series in the 1960's for the heavy fuels used in those engines depending on the TBN lot's of time we had up the ash content to balance out the TBN depending on the fuel fwiw and now there is no heavy ash content in any C rated oil, I don't care what the web sites say I read the jug and Delo 400/40w works in the MTU 2 strokers  .05 ash content

[muldoonman]

Thanks for the info. Will check it out. It a heck of a lot easier to find 400 that's for sure. I use it in all the rest of the equipment here at the place.
