Gas for chainsaw...

[ponytug]

Yup, Seafoam and Stabil in all the gasoline, and Optilube Summer+ in the diesel. ULSD just doesn't have enough lubrication for older diesel engines. I can, and have walked up to gasoline engines that I haven't used for three years and had them startup no issues.

I buy Chevron and Shell gasoline only.

I also switched to metal fuel cans to limit moisture absorption into the fuel which helps reduce oxidation and acid formation in gas, and algae growth in diesel.

All the best,

Peter

I've never heard of Optilube. I run a 100:1 2-cycle mix in my diesel. Moisture absorption is caused by a bad lid seal.

The reason for ethanol in gasoline

Actually, the REAL reason for corn alcohol in gasoline is to support the corn lobby and not much else and it's a proven fact, many times over that it takes more energy to distill a gallon of corn alcohol than the gallon produces in energy.

Without government subsidities no corn alcohol distillers would stay in business.

Get your facts straight...

Do keep in mind I am a farmer but I don't grow e-corn and never will.

You might want to look into the Optilube XPD and Summer+ products. They appear to have exceptional lubricity. E.g.

I don't use the XPD version because of the cost; I use the summer+ version at a slightly higher addition rate, and use SeaFoam to pick up the detergent aspects of XPD. Reading the Optilube Summer+ MSDS label, it would seem to have a significant biodiesel component (known for good lubricity).YMMV.

All the best,

Interesting Peter. Never had a lubricity issue with either of my Kubota's and remember, one has over 6000 hours on it and the other 4000 hours, mostly farming so they get used hard. Same with my 97 diesel pickup truck, never had an injection pump issue or injector issue with any of them. All any of them get is a dose of biocide, nothing more and the last time the 6000 hour tractor was in the shop for a tune up and valve adjustment, the tech pulled the injectors and the spray pattern was just fine. I don't add anything except the biocide. Never had issue one.

I consider most of those additives as just expensive snake oil. I do use Power Service winter additive in the tractors to aid in cold starts, it gets cold here in the winter. Neither get plugged in and no battery tenders either as there is no electricity in the big barn anyway. I do use Nano Borate in the lube oil which is a cleaner that keeps formations under control but that is it.

Your mileage may be different but I know what mine is.

My experience..

SeaFoam works ....

for some things.

I put anti-coagulant in the fuel for the tractor all winter, Just in case.

Any particular reason? Neither of those are sold locally, but I haven't noticed any difference between what brands are available.

Neither have I Corn gas is corn gas, no matter who retails it. Do keep in mind that with the new Federal mandate that corn gas can be 10% or 15% corn alcohol, the 15% can be death on air cooled small engines.

Does for me as well (Seafoam), at least in my GDI Ford engine. Keeps the carbon buildup in the dry intake under control and the catalytic convertor working fine. Every oil change I 'inject' 8 ounces of Seafoam into the intake tract with a warm engine, between the MAF sensor and the throttle body, shut it off, let it sit for an hour and fire it back up and blow the crap out (lots of whitish smoke). been doing that for at least the last 100K miles, every 5K miles. All I use it for actually. Like I said, diesels get biocide and Powerservice winter blend. Been down the algae road and it's not a cheap date, by a long shot.

Yes, the amount of detergents and additives in the gasoline relative other brands. Could you add your own back in? Sure.

At some level, I think that if you don't notice an issue, I wouldn't sweat it. I had a low quality gas experience with my first car (1 tank full!), that triggered new plugs and new fuel filter($$). The week prior, I had just done a tune up and replaced the plugs which were ok, but it was time. A tank of bad gas later, I was convinced that I had missed something badly in the tune up. When I checked, the plugs were black and covered in gunk. Could it have been something besides the cheap gas? Sure. Could somebody have poured something like sugar in my tank? Sure, but I don't know of anyone who would have wanted to. Since that experience, I haven't worried about difference in premium pricing for "top tier" gas, since I now know firsthand the downside cost. I do try to follow gasoline research to try to stay abreast of the field.

YMMV! My "system" works for my equipment in my climate.

All the best,

Peter
