I like to run synthetic in my 318 for two reasons. One I do not put alot of hours on it and change the oil once a year. Two most of the hours that I do put on it are blowing snow and I want that oil to move quickly after start up.

I like Amsoil. I believe Amsoil was about the first with synthetic,having been around since 1972.

I ended up with Napa Full Synth 15w50. I wanted the heavier little number due to the remaining fall heat we are getting. Nothing like 80's during the first couple of weeks in October in Nebraska. It definitely starts easier and seems to run cooler than with what was in it when I got it. I love the k301 but loath the Walbro carb on it...

Travis,

How is the 15-50 syn working for you? I've been using 10-40 syn in my 316 Kohler for about 20 hrs. I'm still seeing a few shiny specks in the oil after my first oil change. Not nearly as much as my previous change, but still there. Thinking of upping to a 15-40 or 15-50 synthetic for better protection. I only use my tractor for mowing and pulling a core aerator.

I've got about 10 hours on it so far and I am happy with it. Oil is still clear but has a slightly darker color than the original gold.

I talked about the oil weight with the local Napa guy before the switch. Because there is no oil pump he suggested something that would cling better when cold. Summer called for 30 wt and winter calls for 10w30 so the 15w50 seems a nice compromise. He did not have a 15w40 in stock either. I gave it a try because it is a newer/low hour shortblock. I did add some Lucas Oil Stabilizer (like a cup or so) to it per his suggestion. It helped reduce the oil consumption issue with my k181 in the 110 and I saw nothing to loose in trying it on the k301.

All that being said - It has not used a drop during the time I have ran it. As mentioned before it is quieter and smoother, especially since I got the carb adjusted correctly. I am really impressed with the 120.

That is great news.

I didn't realize the old 300's were suppose to have 30 wt in the summer, but it makes sense, most every other small engine of that vintage uses straight 30 wt.
The 10w-30 that I had in it this summer has worked fine with no consumption, but like you mentioned no oil pump so it's better to have something that will cling to the interior walls of the motor.

My mowing season is coming to an end for this year, so next year I may switch things up a bit and try the Amsoil 15w-40.

I think Amsoil has an oil that is specifically for engines that were designed to use 30wt. They have so many different products it's hard to keep them straight.

I don't know if the newer long block shows calls for 10w30 or not. This is all based on the conversation with the old skool parts guy at Napa. I might be wrong... and frequently am.
