WHEN I go to pull the starter cord on my torso lawn mower, I don’t get a clean pull. I just gets that sputtering sound we all hate. It’s annoying (and it feels like a personal affront).
But most of the time, it has nothing to do with either fuel mixture or spark plug. It’s typically about oil: Using the incorrect thickness makes for an otherwise trustworthy machine that will overheat, especialy if you transition from spring to summer weather. Keeping Toro engines running well requires that they be precisely lubricated.
How To Choose The Right Oil For Toro Mowers
Common Mower Starting Problems
That’s not as simple as you may think, you can’t just assume any motor oil work. Small engine are not like car engines. They operate at higher RPMs and temperatures in relation to their size.
Using incorrect fluid can cause circulation issues or worse yet lead to sludging up your engine. Use the right oil. This extends the engine life and keeps it cool.
Choosing the Right Oil Grade
SAE 10W-30 is the right grade for most newer Toro mowers. For many reasons, this medium-grade oil covers a broad temperature range. Because of that double digit, the oil flow readily on those cold spring mornings to protect engine parts from wear and tear.
After warming up, the oil becomes just thick enough to cushion moving parts while also resisting breakdown, sludge; as temps rises with the day’s heat. Certain engines requires other grades, so read your owners manual (older versions). Older Briggs and Stratton engines used in some Toro units like straight SAE 30 when it’s hot outside.
That’s a heavy oil designed to keep its thickness at higher temperatures but is hard to start on cold mornings. If you live in a warm constant climate, straight 30 is fine. Switching to a synthetic oil is also not something you should of fear.
Benefits of Synthetic Lubricants
Actualy, it’s usually better and safer. Synthetic lubricants deals with heat extremes better than conventional oils do. Small engines reach very high RPMs and the synthetics are able to hold up better against those conditions.
The engine will be better protected and won’t need changing as often. Upfront price is higher, but good on your engine in the long run. Never mix oils.
Always use a single type and brand so you get consistent results from your lubrication. Chemical reactions can occur between different oils, reducing their lubricating ability. In addition, it produces an unstable condition in the crankcase.
Consistency will keep the engine going strong season after season. Before each mowing, check the oil level. Use the dipstick to ensure fluid is between the marks.
Proper Oil Level Maintenance
Low oil levels will cause immediate damage by allowing metal to grind against metal without any cushioning. Overfilling is equally undesirable: It creates foam that robs the oil of its lubricating properties and result in leaks. The right amount are best.
Regular Oil Change Schedule
Each year (or after 50 hours), change the oil, Running an engine without changing the oil mean contaminants have time to accumulate. Failing to perform this simple maintenance will shorten your engine life. Not to mention it’ll save you thousands of dollars on repairs down the road.
Your engine will deliver steady power and starting performance.
