what type of oil in your off road lawn tractor?

Hwy guys, i just wanted to know what type of oil do you guys use in your tractors? I heard you should use Castrol HD30 SAE 30, is this a good choise for the summer? Il be doing alot of driving and wanto know whats best for torque. any suggestions?

well if i don't have much money i always get Briggs and stratton 30 weight, but if i have lots of money i get a good brand like mobile 1 fully synthetic 10w 40 for hot long uses. and the 40 weight of mobile 1 has oil seal conditioners for older engines, but i only added alittle bit of lucas heavy duty oil stabilizer of what was left from when i added it to my car so not much was added to my mowers, but the lucas stuff is amazing, if you have an oil leak or it burns oil put that stuff in, not the whole thing maybe 1/4 of the bottle and rest regular oil, and it helps the oil withstand really high temps and also lowers friction due to its slimmy feel.

I put SAE 30 in all my stuff. If the engine doesn't have hydraulic valve lifters plain old 30 will work the best during the summer.

Ive used everything from 10w30, 10w40 , 5w30 and sae 30 weight- most suggested oil is 30 weight by manufacturers.

If you change/check it regularlly- dont over rev the motor it should be fine.

As added insurance in y tractors i use Lucas oil motor oil additive - a few ounces every oil change- ive never had any motors let go on me.

I run mobile 1 fully synthetic 10w 40 too, i just put that in my 97 craftsman.
Penzoil is good too.

I forgot to mention- i used to use havaline alot ( cant find the stuff anymore) and castrol - then i found out BP makes castrol , so i quit using it ( why fund thier screw ups in the gulf- make them suckers pay out of thier pockets).

Most time i use valvoline, penzoil , quaker state - i bot some mobil 1 on clearance - i change them often enough to not really worry.

Normally I just run generic SAE 30 , or Motomaster lawn mower oil, in the winter when it gets REALLY cold that SAE 30 won't flow I use 10w30 or 10w40 (generic brands) and lately I've been using heavy-duty diesel 30 weight, as our mowers are used harshly, seems to work very well.

I run the cheapest oil I can find. 30wt in the summer, 10W30 in the winter. It doesnt really pay to use the expensive stuff because you should change it every season anyway. Most of these tractors dont have filters so changing the oil is how you get the impurities out of the system.

Synthetic is overkill for garden tractors, costs way to much and since you have to change it regularly anyway, why spend the money.

I agree, I change my oil more often than recommended even, for what it's worth, about 4$ a change.... Keep a motor like new is worth it in the long run.

I just bang 10w30/40 in my motors. Always seem to start fine, even in the winter.
I just buy large 5 litre bottles for cheap from the cash'n'carry.

Yeah me too, walmart over here by me was good oil in 5qt jugs for 15-20 bucks, thats what i always do.

Id like to try some royal purple in mine, I just put that stuff in my car. Works well, and it lasts alot longer. Also keeps engine temps down, thats why Harely guys swear by it.
