Unless the pump says on it Certified or Guarantied 100% Ethanol Free it will at any grade . Plus the stations are allowed to put in up to 10% Methyl Hydrate (more alcohol ) . Year back when I was still doing Drive Clean Repair , I did a weekend seminar on fuel additives ect. and there effects on the engine . Second day we were to bring in a sample of gas from local station and we did lab tests on them . There was anywhere from no alcohol present to 28% in one sample and that was "high octane " . After that I started running Sea Foam in regular gas year round and have never had carbon , pinging, or carb issues in anything I own since then and that was about 8 + years ago. Sea Foam although flammable is not as easy to light as gasoline helping to raise the octane rating . I have had costumers bring in the equipment telling me that it was't running right and now will not start anymore . I ask them what did you do , and they said put Sea Foam in it . Ok , how much ? The whole bottle they said . Well a little didn't help so kept putting more in they said . More is not always better . Long story short the carb was gummed up from ethanol and there was so much Sea Foam in it the fuel wouldn't light . Cleaned carb , drain & refill fuel and educate customer on proper use and preventive use of Sea Foam . No more problems. Sorry to be long winded , only way I know how to educate people on this .

Thanks Dave! But where can you getting seafoam cheaper!! Because it's not cheap. I put some seafoam in all my engines sometimes but not religiously.

Ya, I sure don't like the $3.89/gal for high test but getting no ethanol for me is worth it. Right now that's $0.70/gal more than regular.

I know there has been a lot of discussion on if it makes a difference or not, and there's a lot of places people don't have a choice. Also, I believe that results vary by what additives are being used by the suppliers, where you live seems to matter.

My biggest improvement is storage time for the fuel. Getting things started has been greatly improved, especially things that don't get run often. The 2-strokes really like it.

I haven't played with using regular and adding Seafoam all the time. I have noticed that Ingy runs better when using Seafoam every few tanks, so I've been using it more often in everything.

Seems that where ever you look there is always different answers. Any way, right on the air cleaner it says , do not use premium gasoline. So that answers that. So I thought I’d look at a few things. Took a spark plug out to see what it looked like. Was a light coating of black on it. Ok, checked the gap. It was right. No wear on the plug either. Then I thought, are they the right plugs. So started looking for plug information. So couldn’t find what I was looking for. So I’ll ask the experts. What spark plug is to be in this B43M Onan engine ? NGK in it now. BR8HS. Looks the same as a Champion H10C.
Checked the points setting and it was at 0.017 suppose to be 0.021, so I read. Would that advance the timing or retard it set at 0.017 ?

Everybody from CTC, PA, Part Source to automotive part suppliers around here carry it . I watch for sales .
No it is not cheap , but think of it this way . 8 oz can will treat 20 gallons / 91 litres of fuel divide by $15 tax in $0.75 / gallon or $0.165 / litre . What is the difference between reg. and high test ? Around here it is about $0.25 per litre . Do the math . I also get better fuel millage using it all the time . It can be had cheaper in 1 gallon cans but not everyone caries it like that . Every time it goes on sale I stock up. I prefer the 8 oz can as they are easier to handle .
Personally I swear by it , but everyone needs to do what works for them .


Dave

Noel, I don't think the NGK BR8HS is a good cross reference for the Champion H10C. It is a marine spark plug, and has a resistor too


I used the NGK B6L as a replacement, from Canadian Tire I got.

Agreed it does not cross over might be close but not right .

I got it last time from Napa when it was on sale. I never really thought it made such a difference, but I'll put a watch on it from now on to stock up again.

But according to the manual the H10C is the right plug for the Kohler K321, and is not the right plug for the Onan B43M. The right cross reference plugs for the Onan B43M are:

1. Champion RH18Y
2. NGK B-4L/3112

If you look at the specs of the B-4L, it has a 1 Kohm resistor, whereas the plug you have now has a 5 Kohm resistor. I'm not saying it'll solve your pinging, but you may as well get the right spark plugs, they're not expensive.

I mean, in theory the resistor should not affect the actual performance. But the heat range of the H10C is 10 and of the RH18Y is 18. This can actually make a difference, especially if there are other factors at play too.

For NGK the lower number is actually a hotter plug. So the H10C that you're running now, which is an equivalent of the NGK B-6L, is a colder plug than the B-4L is is what Onan recommends. How is that for confusing?

Yep, well I’m not a plug expert by any means. Hehe. But I guess what I meant was , that it just looked the same. I don’t know much about hotter or colder plug and resistors. On older cars it was knowen to put a hotter plug in engine if it drives around town most of the time and a cooler plug for highway use. And this would be 40 or more years ago. Today’s vehicles are not like that.
I’ll find a set of plugs some some day I’m out and put them in.
