MEP-003a oil changes

Can someone tell me what the spec. engine oil is for the MEP-003a? I'm guessing it'd be safe to just use Shell Rotella T 15w40?

Thats what I Use

Honestly, any brand of diesel 15w-40 oil you want to use is just fine for those engines.

And always remember, I have the spin-on oil filter adapter kits available for sale!!!!

WalMart had Cheveron Delo for $8.50 a gallon. That is what I use in Diesel stuff here in LA.

Saw 2-18-10 post on this topic. Suggests not use multi -grade oils in air cooled units.

"Are these air cooled engines? Multi-grade oil is a no-no for air cooled engines, the high temperatures will burn the viscosity-modifying polymers and the oil will break down. Straight 30w is the way to go.

Jon"

Can anyone clarify best practice?

We always used straight 30W in the military. I have 15W40 Rotella in my personal MEP002 with no problems.

ive seen a lo with 30 and 15-40 recomended. i guess in cold climits below 30 degees the 15-40 would be the way to go. i use 30 rotella in all my 002s but dont see temps. like that exept maybee 2 or 3 times a year.

Yanmar calls for 10W30 so I assume multi viscosity is OK in them.
I don't think a good oil would have a problem in most air cooled engines.
What does Onan say about the commercial air cooled sets?

The generators have a pretty good oil cooler and at 100 hour oil change intervals prescribed by the TM I doubt you would wear out 15-40. I use Rotella 15-40 in mine as well.

Mr Speddmon, are you still selling mep003a oil filter adapters? I need two. Please contact me if you do. My email address is geraldrowell@bellsouth.net. Thanks

Well, the LO lists OE-30, unless the temp is below freezing.

Does someone still make a spin on conversion for the mep003?

That is correct! I will send you a PM , as it looks like you have insufficient post to send me one.
Thanks for the plug Guy!

How many posts does a guy need to make to be able to send a message?

Somewhere 10-15 I think. Rays kits are top notch quality.

It will have to be Lunch then.... with your brewing background I suspect any beer I could offer you from America would rate somewhere between inferior and insulting. possibly even undrinkable!

The LO and manual are in the FORUM. Wish the ARMY used that spin on filter adapter one member has. Would have saved a lot of money. The engine manual breaks this down well. The wide spread use of 15-40 was due to US ARMY TACOM (Tank and Automotive Command) and their engine lubricant research folks wearing white coats and funny glasses stating ARMY wide to use 15W40 as this was the main oil used ARMY wide as ordered by TACOM and available. Engine design was based on 30 weight which is the major part of 15W40. Temps play a roll in this as you have to get the engine started on those icy days when power fails at home. 15W40 worked around the world in all normal Temps on everything running a piston engine. They were asking everyone as i retired for an oil that was universal, but not passed by any generator engine manufacturer. Now this is clear as mud so I Wish all a great day....
