I swear, Paul, you have the funniest posts on the board. I'm still laughing at your "direct vs indirect" post.

And, no, her name isn't Eve, but that's close. Her name is Eve spelled backwards.

Another dumb question for the syntetic oil experts. I'm going to use the Amsoil 15W-40 Diesel and Marine oil in my two Kubotas. Is there any reason not to use the same oil in my two Jeep Cherokee gas engines? Thanks.

JBM - I dunno. I'd first like to know what your manual says you should use for the most typical temperature range you're likely to encounter. It probably recommends 10w30, in which case I'd suggest you use a 10w30 or 5w30, not the 15w40, unless the engines have a substantial amount of wear on them. If so, you'll want to flush them, too.

Mark, when I change the Dodge over to the Amsoil should I flush it as well? It's got 80,000 on it?

 

[PaulB]

Jeez Bill, a Chrysler product with 80,000 miles on it. Do you have the original engine in there? I'd say it is indeed time to flush it, but maybe not in the sense you were thinking.

PaulB,
I really don't see myself as a Chrysler kind of guy, but I now own one of their minivans, had one before this one and even owned a Volare' before. All had/have well over 100,000 on them with no major problems. The Volare' had the old slant six in it that would start in all weather no problems. My major problem with the vans has been all of the recalls! JimBinMI

 

[PaulB]

Jim - I appreciate your advice on the merits of Chrysler products, but I guess I have to take it with a grain of salt seeing as you also own a , well, um, you know, one of those plastic bodied swoopy blue things you generously refer to as a "tractor". /w3tcompact/icons/smile.gif

Thanks, Mark. I'm not really trying to be a pain - just would like to reduce the number of different lubricants cluttering my garage. The Jeep manual says to use an oil "API certified for use in gasoline engines...viscosity determined by the lowest air temperature expected before the next oil change" The chart in the manual says 10w-30 is good from 0 to 110 degrees F. Now I just need to find out if an oil certified for diesel means that it is also certified for gas engines -- and at what engine/air temperature does a 10w-40 oil actually "thicken" to 40 weight? I know... I'm thinking about this way too much. I will call the Amsoil people and see what they say.

 

[MChalkley]

BillC, I would. That's long enough to need it, I expect. Amsoil makes a flush, too, if you're interested.

[MChalkley]

PaulB, it's not just "a Chrysler product" - it's a Chrysler product with Cummins diesel engine in it. There's a difference. /w3tcompact/icons/smile.gif

[MChalkley]

JBM - your questions are all valid ones. I'd use either 5w30 Diesel or the 10w30 'Turbo' in them. All the Amsoil diesel oils I've seen also meet every gasoline spec in common use. Let me know what Amsoil says, if you call them.

I swear, Paul, you kill me! (Sorry, I still have to learn those little facey things!

Billc, Click on the "FAQ" and read the "Can I use HTML in my posts?" section about the "Markup" and you, too, can make funny faces./w3tcompact/icons/wink.gif/w3tcompact/icons/smile.gif/w3tcompact/icons/laugh.gif

[Billc]

Thanks Bird.

PaulB, now how can you pick on a Dodge diesel. Are you still not getting enough sleep? I mean it has THE engine! This comes from the voice of experience. My last diesel pick-up was a '85 GMC. All I'll say about that piece of crap is that at about 70,000 miles the engine blew. I now have the advange of having a Ford 250 diesel and a Dodge 3500 diesel. What a difference in engines, Paul. Just the other day I taped both engines. I came in and listened to that sweet sound of the Cummins, and then to that whimpy spattering noise the Powerstroke makes. Then I decided to slow the tape down and listen to the two engines. God, when you listed to the tape of the Cummins slowed down by 50% you hear "BHA DA DA DA DA DA DA DA..." But when you hear the Powerstroke tape slowed down the same amount you hear "far-fet-nu-gan, far-fet-nu-gan, far-fet-nu-gan" (This is not meant as a cut to Mark and his Volkswaggon)

 

[MChalkley]

BillC - Good one! /w3tcompact/icons/smile.gif

But did you know that if you play the Powerstroke tape backwards, you get "When I grow up I want to be a Cummins"??? /w3tcompact/icons/wink.gif

[PaulB]

Bill - we all know about the mid 80's GM disel experiment - everybody makes mistakes now and again. I am sure the Cummins is a great motor, and I am sure it will outlast the crap of a truck that it sits in too! Now, a Suburban with a Cummins - that would be sweet.

 

[JBM]

Where's the "off-topic" police when you really need them.

MarkC - here's what the Amsoil tech guy said: Any Amsoil API diesel rated oil can be used in a gas engine because the the criteria for being rated a diesel oil is more stringent than for a gas-rated oil. As for viscosity, the 15W40 Diesel oil is close enough to the 10W-30, especially here in Florida where the air temperature rarely falls below 30F, that it would be fine for use in my gas engine Jeeps. Also found out that viscosity is measured in "centistokes" (not sure of spelling) at 212F(100C), and that it is a measure of resistance to flow in square centimeters per second through a specified diameter orifice.
In addition, he says that the same Amsoil Diesel oil is fine for use in the small 4 cycle engines (B&S, Tecumsuh, etc.)I use to run an irrigation pump and an AC generator. Sounds like I can reduce the number of containers on on my lubricant storage shelves.

PaulB - I heard about a guy who tried to put a Cummins engine in a Suburban but he couldn't keep oil in it - it kept throwing up. He ended up putting it back in a Dodge and it was fine. /w3tcompact/icons/wink.gif
