Synthetic Small Engine Oil (ASE)
A commercial grade formulation designed for hot temperature, severe service operation of small engines where routine maintenance is often difficult or infrequent. Recommended for use wherever SAE 10w30 or SAE 30 oil is specified in gasoline or diesel engines, transmissions, hydraulics, and chain cases requiring the listed specifications. Applications include maintenance equipment, tractors, lawn and garden equipment, generators, compactors, pumps, light towers, welders, log splitters, power washers, cement mixers and trowels, skid-steers, excavators and compressors.

This is a gas oil as well.
PRODUCT DESCRIPTION
AMSOIL Formula 4-Stroke® Small Engine Oil (ASE) is a robust formulation designed for hot temperature, severe service operation of small engines where routine maintenance is often difficult or infrequent. It is formulated with premium synthetic base oils that exceed both 10w30 multi-grade and SAE 30 straight-grade viscosity requirements. Unlike conventional SAE 30 motor oils, AMSOIL ASE has a naturally high viscosity index and does not contain paraffin (wax). It has a -38°F pour point and qualifies for SAE 10W, making it an "all season," multi-grade lubricant with a wide operating temperature range. As an SAE 30 weight motor oil, AMSOIL ASE provides outstanding protection for hot operating engines. Formula 4-Stroke® Small Engine Oil is a commercial grade lubricant that helps improve productivity and reduce maintenance costs through superior engine protection
 
Sounds like it would be good in those "fill for life

" tuff torq hydrostatic trans that spec 10w30 but are a royal pain to change the fluid.
 
I understand that HONDA is requiring a 10W30 oil for the new 2007 bikes.
I'm wondering if this will fit the bill as well.
 
Don,

I'd think the 10w30, Four Stroke Marine oil would be even better for those bike applications. It's quite a bit thicker in terms of high temp, high shear viscosity.

That may work as well. Looks like thinner is going to be the standard for the future.....guess I better keep excersising

So which one is better? I have been using ACD in my comercial mowers. I noticed ASE is a little cheaper and is actually labeled for this use.
 
This oil has been discussed here before.

The ASE is NOT the same as any other oil in AMSOIL's line up. It is a PAO with an additive package similar to the 4 stroke outboard oils. At first I thought it was a repackaged ACD 10-30/30 but it is not the case. Info from AMSOIL U.

I think this will be a great oil for motorcycles needing a 10w30 as it is JASO MA.
 
I just looked at amsoil website and compared. In my opinion if I am going with amsoil that is a 30wt/10W-30 rated I am gonna go with tha acd not the ase just because the acd has a tbn of 12 while the ase only has a tbn of 8.4. The price to me would be any problem. But I do see you guys considering the ase because it is available in quart containers while the acd is only sold by drums or gallon jugs.
 
Thanks for the info Don. Looks like the perfect product for us old timers that can't make up our minds!

Old school: straight 30 wt. in all lawn type air cooled engines.

New school: even Briggs now recommends synthetic 10w30 in their throw away engines.

THIS OIL FITS THE BILL FOR BOTH SCHOOLS OF THOUGHT.

It's also good for us commercial guys that use various engines that spec both weights. That is why I have been using ACD for a few years now.

I don't know about 10W30, but Briggs sells synthetic 5W30 under their own brand name, and recommends it for all temperatures. They specifically recommend against using dino multigrades, stating that such usage might lead to excessive consumption.

Yeah, not the story with my 1997 b/s 14.5 I/C air-cooled with that Castrol GTX 5W-20 in it's sump. Been in now for 18.5 hours and is still as amber as it was when it was put in and is still at the full line. Not a drop of oil consumption.
 
According to the old school of thought an oil even a synthetic oil is EITHER a monograde or a multigrade and it cannot possibly be both at the same time. So according to the old school if your engine requires a straight grade oil only a petroleum monograde will work in that application. I am not saying that the old school of thought is right but the old school is usually very much resistant to the concept of universal oils designed for a wide range of applications. The old school may accept a synthetic monograde oil but it must be cleary labeled SAE 30 only.
