I'm gonna have to run over to tractor supply and see if they still have some then. I run SAE 30 in the rest of my power equipment, so I switched to that VR1 that H80N mentioned in the beginning of this thread. The parts house I frequent stocks it regularly, so that makes it convenient.
    Ryan;

    TSC., just has the T5, not the Synthetic T6 on sale here in Ontario.
    The T6 Syn. oil is what I'm going to use from now on.

    I listen to what cruizer says because he sees the inside of engines that he services and ones that someone else serviced , so he knows which oil works best.
    Now the engine oil people won't tell you all of what they see and a generator or lawn mower tech wont go through there engines usually they just sell them because it cost to much to fix them but a welder generator engine may be worth fixing so cruizer gets to see a lot of insides.

    This thread is livng proof a guy ca study till his eyes bleed and still not know much more than he started out with. TSC has had the best deal lately on T6, put it in and forget about it, learning everything about oil thru a month of study and it would have been cheaper to replace it, not that it likely makes all that much difference.

    Thanks for the advice on the Onan. I put the Onan oil in it yesterday and probably stick with it at least until I understand all the oil ins and outs.



    I've been up to Canada a few times, never made it to a Canadian tire though. Loved the Tim Hortons coffee though!

    I've owned a few onans in the past and this is the first one without an oil filter, I was actually sort of surprised.

    ...soup to nuts eh? But do they have tires?
    Tires - Yes, Ryan they do.
    It's similar I think to the American Lowes stores.
    Just about anything you can think of, for the home, office, work shop, automotive & etc., etc.

    The longest I've heard of a ky running was on the onan oil. I would stay with it while under warranty.

    Thanks Norm. The Onan and rotella I got are both CJ-4. I haven't had the time to sit and read through the technical stuff on that link. You know how it goes, sometimes more in a day than hours to do it.
    I hear ya, Ryan.
    But if you have the time, it's a good but tedious read.......... lol.

    Good info.
    If you can find the Rotella T6, which is the synthetic form, it has All the Good stuff, as far as I can figure.......... LOL.

    Maybe try Wal-Mart, here in Canada, we have a place called Canadian Tire which has everything from soup to nuts...........lol.

    Ok, for an Onan generator in an RV, the Onan shop sells onamax 15w-40 for my unit. The bottle doesn't say diddly squat about zinc and all that other stuff you guys are talking about. But it has a bunch of those letter designators...CJ-4, CI-4 plus, CI-4, CH-4, CG-4, CF-4, CF/SL<br />
    <br />
    Any of that good? I also got some rotella T triple protection...but the bottle on that doesn't say anything about the good stuff and it has a bunch of letters too. <br />
    <br />
    I went looking for the rotella T6 in a 15w-40 but my local parts source doesn't carry it and isn't sure if it's available. <br />
    <br />
    My RV is less than a year old and this is my genset first oil change at 66 hours. What say you gents?
    Ryan - Going by what H80N posted above. From what I can gather the CJ-4 & SM are what we are looking for.
    Click on the the links & read them - Good info. A little tedious ,but interesting .I bought the Rotella T6 - 5w - 40 locally here. It's the synthetic version, which is all I've ever used in all my machines. ( Welder, Compressor, & Truck. )

    I was thinking it was an abbreviation for something. Probably why a Google search just brought up a bunch more two letter tags without an associated two word definition. You guys are super smart. I have no idea where that would fall into API terms.
