Design for smaller engine. I notice the oil is not dark looking after 50 hrs of service. If u want the Best Buy AMS oil

The best product on the market... after running amsoil in all my vehicles/toys.... the results are incredible. I do all my own repairs/service work. Tearing down engines,cylinder heads after using this product is unbelievable. No sludge no buildup of deposits..... 200.000 miles and the bearings look brand new. I will use no other product!!!!!

Withstands high and low temperature extremes, longevity, extreme harsh running conditions, long lasting protection

Im tickled as can be with the Amsoil Small Engine 10/30 oil. It really keeps the generators i run going and going. It seems now the engines outlast the rest of the equipment that uses Amsoil. The mower, generator, and tiller all run excellent engine wise, but now if the makers could get the rest of the equipment to last as good as the engines with Amsoil in them.

I have been using amsoil products for over 20 years in everything I own. Never an issue or a problem. Easy to purchase, engines stay clean and run well.

I've used this oil in mowers, tractors, and other yard equipment for years with no problems whatsoever. Great stuff!!!

I have used AMSOIL in my cars and motorcycles and they have protected my engines wonderfully!!!

All my small engines.

Great product, use it in all my vehicles, motorcycles, snowblowerand lawn tractor. Been using Amsoil for many years and will keep using it.

I use 10W-30 Synthetic Small engine Oil for all of my small 4 stroke engine services brush trimmer, lawn mower, this includes my Generac standby generator & portable unit.

Great oil. Use it, in all my small engines.

I use Amsoil in all my small engines, they start easier, oil stays cleaner and engines give me the best service.

You can use this in ANY small engine it seems like from mowers to snow blower to generator Those items that i don't keep good records on, I know are protected!

I have several machines that i use the oil for, a large snow blower, a large leaf vacuum with a chipper, and a self propelled lawn mower. I use AmsOil in all of the machines. they run trouble free and i maintain them and change the oil at the intervals. I couldn't ask for a better oil, than Amsoil.

Use fo the lawnmower

I use this oil exclusively in both my Toyotas. I was in WI right after Christmas. Temps up there were in the -6 to -17 range. Thank you Amsoil because my van turned over like it was 75o out. Fired right up and ran perfectly. This is where synthetic oils shine - during extreme temperatures. Amsoil has never let me down.

I use the 10W-30 in my 1998 toyota camery. The engine in this vehicle has a history of making sludge and Toyota has even had a lawsuit over this. For this engine (2.2L) Amsoil even recommends changing the oil at the scheduled interval recommended by Toyota which is 3000miles even if you are using their signature series. I change it every 6 months (once before winter and once after) roughly 7500 miles on each change. Never had a problem. 270,000miles on our 1997 toyota camery and running strong until it was totaled in a car reck, 150,000 on the current 1998 and I expect to get another 150,000.

I use Amsoil products in almost every application I can, from 2 cycle hand held power equipment to diesel engines to grease. I am a firm believer in Amsoil Synthetics.

Great Oil at a great price. have been using Amsoil in my tractor for 12 years now and the motor is as strong now as the day I bought it.

I have used this in my lawnmower since 2000. My snapper is 34 years old and still running on the original engine
