Can I use 15W40 instead of 10W30 in lawn mower?

Yes, although it would flow slower when cold and would be about 30% thicker when hot but not enough to make much of a difference as long as outside temperatures are above 50F it will also burn less if the motor is using oil but if the motor is solid and not smoking it’s best to stick with the 10W30 oil.

What happens if you put diesel oil in a gasoline engine?

Diesel oils have to put up with much higher engine temperatures, higher oxidation rates, sulfur deposits, fuel soot, acids and other deposits and conditions not usually found in automobile engines. … It’s because diesel oils fail in one critical area when used in gasoline engines.

What happens if you put diesel in a lawnmower?

The fresh gas will dilute any diesel left in the tank. It may smoke and stink, but mowers are low compression so it shouldn’t hurt anything. If it’s smoking too badly, drain the tank again and refill with gas again and you should be good.
