Mobil 1 is bad for Air Cooled Mowers???

Original post: "It does make me wonder about an air cooled engines and full synthetic."

Synthetic motor oils have been widely available and used for a several decades now. If there were common incompatibilities or Martian green slime issues when using syn in grass chewer applications, that would have shown up in Honda, Tecumseh, and Briggs & Stratton owner's manuals by now.

Amsoil 4 Stroke and be done with it.

I would also say take the story with a grain of salt or as an OPE urban legend. Maybe someone put the tire slime in the wrong place.

The guy may know how to repair equipment, but like many shops they don't know squat about oil. LOL

What he told you sounds like nonsense.

I have been using M1 5w40 in my Kohler command 20Hp engine in my Cub Cadet 2544 for about three years now. I do one year changes which may total up to 50 hrs as mostly i push mow my yard just for the exercise. These engines are known to run hot. In my push mowers, generators, tillers, and power washers i use whatever HDEO dino i can get on sale. Mostly rotella but i just found some Delo 400 on sale for 15 dollars for 2.5 gallon jugs. I bought six of them so im in good shape for ohh about 10 years.

If Mobile 1 is poison for air cooled engines it must be slow poison. The Tecumseh LEV-80 on my lawn mower has been living on the stuff for 14+ years now and has never been apart. It even has the original Champion spark plug still.

Don't listen to small engine repair dudes. They know how to fix carburetors and not much else.

I've used several oils in my 99 Sears garden tractor. It recommends 10-30 oil. I've used Castrol GTX, Quaker State, and Mobil 1 in it. All but the Mobil 1 turned green. I'm still using the Mobil 1, changing it 2x a year. It mows a hilly 2 acres, it turns the garden and plows the driveway all winter, I'd say it's hard use. It's just starting to get a puff on startup after 13 years, but I think its the valve stem seals, not the guides.

Well, our local repair shop sells M1 15W-50 for stationary engine use. AND, they came to that conclusion independent of my advice (ha ha) . Nor did I get the idea from them.

They simply repaired hundreds upon hundreds of hurricane-use generators. All with oil related engine failures.

call me dumb but I simply don't see the correlation between (cause and effect) of using M1 and the development of green slime under the cover. Are these green-slime related to moisture?

Working an engine hard is one thing(and syn oil should be capable of handling such breakdowns with ease due to more robust base oil), what green slime is that shop owner talking about.

I personally think this discussion isn't going anywhere unless we have the full details from the shop owner and/or pics to follow. Otherwise: it just classify as "hearsay".

My 2c's worth.


Q.



I think that shop owner has Green slime on his brain.

+1. And I'm going to up the ante even more. I bought my Honda HR194 mower in 1987. I've used Mobil 1 10W-30 for at least the last 20 years. I use it probably 50 weeks a year - winter use is to vacuum up leaves. It has never seen a repair shop. Always starts first pull, no smoke, etc. I worry most abaout the [censored] ethanol gas it gets. I have learned to never buy more than a month's worth of gas at a time so it never gets old.

Multigrade oils used to be murder on small, hot engines because they sheared down and the additives sludged up as a result when they fell out of the battered oil.

These days? Nah. Fine. Just watch if it burns oil.

Yeah this is just another thing being forced on us that we have no say about.

WMS, I believe this slime may be related to all the ghosts that haunt our MTD plant here in Cleveland. I think this is a localized event
