I bought this snowblower two and a half years ago under the assumption that it was on it’s last leg. The guy I bought it from had no clue about maintenance and thought he was ditching a lost cause. Thanks to AMSOIL I was able to halt the damage and solve a couple potential problems.
Sludge and Deposits Are Common But They Don’t Have To Be
I watch my neighbors struggling to get their snow-blowers started – Mine is no longer a chore to get it going and before it had awful oil consumption. The owner likely just topped it off with oil although it’s one of the easiest pieces of equipment I’ve ever had to change oil on.
It was so black and thick I doubt it was drained in years. I drained it (totally black) replacing it with AMSOIL Formula 4-Stroke Commercial grade small engine oil 10W-30 synthetic (ASE), ran the Quickshot through the tank a couple times (had ethanol in it no doubt), used stabilizer over the summer and cleaned the intake w/ Powerfoam. – Now it starts on the first pull all the time. Started no problem at Zero deg. F yesterday and the oil level is still on the money. (Three oil changes now). Very likely deposits had formed in the rings. The Powerform and good detergent/despersant oil had the ability to increase the compression and reduce consumption.
Stop in to the Sioux Falls store and protect your equipment today!! Cheaper motor oils and ignoring fuel maintenance reduced dependability greatly on these small engines.
Ask about the Powerfoam for all your small engines and carbureted motors. Even if you use 10% ethanol you need to use quickshot. A little goes a LONG way and solved severe fuel problems. Avoid repairs and downtime.
Everyone who owns a vehicle knows you need to regularly check the oil level. (Note: If you do not know this, you’d better go check your oil. and Check your tires too!!
A certain amount of oil loss is normal due to motor oil volatility – that is, boil-off due to the high-heat conditions inside an engine. I once attended two days of training at a quick lube (part of a major oil company chain) wherein they showed how their conventional oil lost up to 30 percent of its weight and their synthetic only 12 percent in a volatility test. It drove home the message I’d already adopted that synthetics were more resistant to oil consumption than conventional oils. AMSOIL synthetic motor oils are even more resistant to volatility. (Read about AMSOIL performance in the NOACK Volatility Test.)
Volatility isn’t the only reason you need to replenish your oil supply now and then. The problem of abnormal oil usage is far more complicated and, in fact, most of the causes are mechanical, not lubricant-related at all.
Some of the many points where external oil leaks may occur include oil lines, crankcase drain plug, oil-pan gasket, valve-cover gaskets, oil-pump gasket, fuel-pump gasket, timing case cover and camshaft bearing seal. No possible source of leakage should be neglected because even a very small leak can cause extremely high oil consumption. For example, it has been estimated that a leak of one drop of oil every 20 feet is approximately equal to a loss of one quart of oil every 100 miles. One way to check for external leaks is to road test the vehicle with a large piece of light-colored cloth tied under the engine. Oil on the cloth will indicate a leak, which should be traced to its source.
I recently burned a lot of cash trying to get an oil leak fixed. The first task is accurately locating the source of the leak. The problem may be front or rear main bearing seals, worn or damaged main bearings, worn or damaged connecting rod bearings, worn or damaged camshaft bearings, worn crankshaft journals, distorted cylinders, worn ring grooves, cracked or broken ring lands, problems with the wrist pins, clogged oil passages or even unequal tightening of bolts.
Sometimes a defective cooling system can cause engine overheating, which may result in localized hot spots in some of the cylinders that can lead to scuffing and scoring of cylinders, pistons and rings, resulting in high oil consumption.
If you really want to sink your teeth into it, causes for oil consumption can include too much oil in the crankcase, worn or broken piston rings, improper valve timing, incorrect oil pressure, piston slap, an internal gasket intake breach, spark knock, aftermarket performance chips and modifications, lugging engines, inappropriate operation of overdrive, leaking turbocharger seals, a restricted air intake and fuel dilution.
In short, few things are as simple as they might initially appear. When all is said and done, however, even though there may be multiple reasons for oil loss, in a mechanically sound engine it boils down to one: oil volatility. In this matter, synthetic motor oil provides better resistance to oil consumption. If you have a mechanically sound engine, you should be using synthetic oil to reduce oil consumption and to protect your investment. In addition to reduced oil usage, synthetics can reduce emissions and improve fuel economy.
During my three decades of writing about oil, I’ve always recommended a synthetic solution.
