Best Engine Oil to use for Suzuki King Quad

[jatho]

What is the best engine oil to use for the Suzuki King Quad - also any other tips and tricks I should know before doing an oil change on these bikes

15/40 of your choice just be sure to run after change at idle then CHK again to make sure it's full

No tricks, very straight forward. Last time I changed the oil I figured I'd buy the good stuff at $12 a quart. My gf comes out and starts talking to me while I'm pouring in quart after quart. Checking the oil fill window over and over wondering why nothing was showing up. Then after all 3 quarts were emptied I noticed I hadn't put the drain plug back in. They were all emptying into my oil pan just out of sight and mixing with the old oil I had just drained so I couldn't even salvage it. Knew I would do that at least once in my life but I swear never again!

Yes sir gf can do that you especially if they're wearing next to nothing on.  Done somethings the same in the past. You live you learn as grandpa used to say.

The always popular "best oil" debate...lol

Hello,

 I'm new here. Interesting topic 'motor oils'. I've been riding motorcycles since the 1960's. I've been riding ATV's since they were ATC's in the the 70's and 80's and still own them. I used to buy the expensive oils from Castrol and even Pennzoil Racing oil which claimed superior qualities. Quaker State full synthetic was my choice when they introduced that. But I don't use that in my older ATC's or ATV's. Wet clutches. Now days with high prices I have investigated Super Tech Oils from Walmart. This oil is a collaboration between three major companies. First Warren Oil owns it. But Pennzoil and Exon Mobil produce it with very high quality standards. It's tested and proven a winner at a much better price. What I have always used is still in the charts in my owners manuals and I could upload the chart if interested. 10w-40 which can be used year around, and 20w50 if you have hot summers in your area, or work your machine like I do. These are my first choices. I have never had any engine failures ever. The 1985 Honda Big Red 250ES pulls a log splitter, a trailer stacked full of firewood, a farm harrow section on a sand beach, and has a snow plow for winter. This machine is a testament to Honda back in those days and the fact oil and filter plus air filter equals longevity. There is a wide range on the charts which give an ambient temperature range that each viscosity is suitable for use in. The two I picked cover everything I need weather wise. If I had unusual extremes cold or hot I could choose differently. Example; 10w-40 conventional oils are good from -4 F to 104+ F.  Super Tech All Mileage Synthetic Blend Motor Oil SAE 20W-50, 5 Quarts $17.36 today, not too bad $3.47 a quart. 

I recently purchased a 1998 Suzuki LT-F500F 4x4 Quadrunner that needs some maintenance. This is why I'm here to listen and learn. I have done my own maintenance on many things from lawnmowers and chainsaws to old cars and trucks to newer stuff and never find an end to learning new things.

Great choice and so is 15w-50 both good until the dead of winter subzero, if you go out then drop that first number a notch.

laugh and cry  we all make mistakes sometimes, I mean with the girls.

Depends on environmental temperatures. Generally I follow the manual and the viscosity that covers the largest range of ambient operating temperatures.

I think 5w30, but maybe 10w40.

So ... there's more than one version of the King Quad. And there's a very important difference. Some, have a thermostatically controlled fan, that blows ( sucks?) air through the oil rad at the front of the bike, some don't. If you got one that doesn't have the fan, either mount one with a switch, ( thermostatic or manual ), or be real careful with high load / low speed stuff in the Winter. Hell of a load, pushing snow at a couple of Miles an hour, with no free air passing over the cooling coils. 

5W-30, or 5W-40.. The 5 is still the same cold viscosity, but the 40 will give a higher temperature tolerance..  Yup.. even in the dead of Winter. I've got an old Honda Foreman, that pushes a 48 inch snow blower in the Winter... The next time I hear the fan running to keep the temp down, won't be the first.

I generally go with the 10w40, but if i lived in the snow belt i would go with 5w40.

This is what I alluded to in my previous comment. This is from my LT250E manual, so it does not apply to your engine, but you get the idea.
