I am sure this is probably covered, and I tried searching for it, and reading the stickied post at the top but didn't really find an answer. Can I just go to walmart and buy 10w-30 oil for my Kholer Courage 22hp mower on my Cub Cadet? Does it have to be lawmower oil or is oil for an automobile fine too? Any oil better than the rest? Synthetic? Thanks!

I don't like GF-4 oils in my small engines. I believe most small engines have a flat tappet cam and therefore would benefit from the higher levels of ZDDP found in non GF-4 oils. The Mobil 1 High Millage line has a higher ZDDP level and I favor the 5W-40 Mobil 1 TDT oil.

The Kohler courage engine does not have hydraulic lifters like the Command series. Therefore the engine should probably use an SAE 30 oil. Plastic cams seem to like it.

Any oil should work fine. I generally use SAE30 in small engines, say up to like 8 hp, unless it says otherwise. I also use SAE30 in the Kawasaki 420V and 460Vs, that is what's recommended. Otherwise I use 10-30 in pretty much everything. You can mix oils too, say you mix on a 1:1 ratio 5-30 and 10-30. You now have 7.5-30. Or 10-30 and 10-40, you now have 10-35. Or so I've heard. Oil is pretty standard, unless you get into synthetics and 2-cycles.

Personally I like Synthetic oil. I've heard it keeps oil seals happy and can prevent oil leaks.

Or save yourself the worries and use Kohler's own oils. Both their 10w-30 and 30wt are useable in that engine. Air cooled engine oils are different than oils for water cooled engines.

Kohler doesn't have its own wells and refineries. They buy their oil from the same company that sells to Walmart.

read the owners manual, then go to the store and buy that viscosity of oil. if it calls for a muliti weight oil then great, if it calls for a single weight then great. In this case your owners manual for the engine is your bible...

The Kohler Oil has an API rating of "SJ" according to their web site. As a rule an API rating higher than SJ should be ok too, but now with the ILSAC GF-4 rating that most oil companies are complying to, this is no longer the case. The Kohler oil does not have a GF-4 rating and therefore is better for Kohler's small engines than the modern oils designed for today's passenger cars.

Yes, you need the appropriate viscosity and, as you point out, API rating too. Beyond this, a name like Kubota, Deere, or Kohler on the container does nothing but increase the price.

Kohlers generally take a Multi-viscosity 10w-30 Detergent-based oil, which is also used as an automotive oil.

10W30 will work fine for your mower if operating in the air temps of approx -(-4) - 100 degrees outside. SAE 30 is better if you mower will be operating in outside temps of great than 32 degrees (e.g. 32-100 degrees). SAE40 is for temps 68 degrees and above. Synthetic oils will give you easier starts in the colder temps, but for no greater revolutions and temperatures that a lawnmower engine has, a synthetic is of no greater benefit than a standard oil.

Multigrade oils such as SAE 5W-30 and 10W-30 are widely used because, under all but extremely hot or cold conditions, they are thin
enough to flow at low temperatures and thick enough to perform satisfactorily at high temperatures.

IF LOWEST EXPECTED OUTDOOR TEMPERATURE IS

TYPICAL SAE VISCOSITY GRADES FOR PASSENGER CARS
0C (32F) - 0W-20, 0W-30, 5W-20, 5W-30, 10W-30, 10W-40, 20W-50
18C (0F) - 0W-20, 0W-30, 5W-20, 5W-30, 10W-30, 10W-40
Below 18C - (0F)0W-20, 0W-30, 5W-20, 5W-30

Hope this helps..It is what I follow and recommend. :usflag::usflag:

How about following the manuals recommendations? Or is just more fun to Frankenstein together part bottles of different weights and brands?
