Why We Sell AMSOIL: The Science of Ultimate Protection

At JOC, we don’t put our name behind just any product. Our custom fabrication and mechanical work are built to last, and we believe the products within should match that exact same standard. Whether you are running a heavy-duty diesel fleet, maintaining agricultural equipment, or keeping your daily driver running smoothly in brutal winters, AMSOIL synthetic lubricants deliver protection that conventional oils simply cannot match.

Here is the breakdown of why AMSOIL stands alone at the top of the industry.

Extreme Temperature Performance

Wyoming weather goes from scorching summer heat to sub-zero winter freezes. Conventional oils thicken up when it gets cold, forcing your engine to work harder and starve components of oil at start-up.

Sub-Zero Pour Point: AMSOIL synthetics remain fluid down to -40 (degrees) F and below. This ensures near-instantaneous oil circulation during freezing morning starts, drastically reducing engine wear
High-Heat Thermal Stability: Under extreme loads or heavy towing, cheap oils break down, thin out, and leave behind harmful varnish and sludge. AMSOIL resists thermal breakdown, maintaining its protective film even when engine temperatures skyrocket.

Unmatched Wear Protection

The primary job of motor oil is to keep moving metal parts from grinding against each other. AMSOIL is engineered with advanced synthetic base oils and premium anti- wear additives that form a durable, microscopic shield on vital components.

Wear rate decreases significantly as oil film strength and additive stability increase. AMSOIL maximize both of these positive variables to keep your equipment running like new.

In independent industry testing, AMSOIL consistently outperforms the toughest specifications:

75% More Engine Protection: Delivers up to 75% more engine protection against horsepower loss and wear than required by a leading industry standard.
Maximum Component Life: By drastically reducing friction, AMSOIL keeps gearboxes, differentials, and high-clearance diesel engines running cooler and lasting significantly longer.

Extended Drain
Intervals

Changing oil wastes time, causes downtime, and burns through money. AMSOIL’s superior chemical stability means the oil lasts significantly longer before losing its protective qualities.

Up to 25,000 Miles or 1 Year: Formulated with exceptional oxidation resistance, AMSOIL synthetic lubricants maintain protection significantly longer than standard oils, allowing you to go up to 25,000 miles or one year between service intervals.
Reduced Total Costs & Downtime: Performing fewer oil changes dramatically cuts operational maintenance fees, reduces spent oil filter waste, and minimizes fleet or personal vehicle downtime.

The Ultimate Proof: AMSOIL vs. The Competition

When you compare the chemical structure of AMSOIL to conventional or lower-tier synthetic oils, the difference is immediate. Conventional oils contain irregular, uneven molecules with impurities like sulfur and wax. AMSOIL’s pure, chemically uniform structure ensures flawless lubrication under pressure.

Performance Metric	Conventional Oil	Standard Synthetic	AMSOIL Premium Synthetic
Film Strength under Heavy Load	Poor (Breaks down)	Moderate	Maximum (Resists shear)
Cold-Weather Cranking	Sluggish / Thick	Average	Instantaneous Flow
Oil Consumption / Volatility	High (Burns off)	Moderate	Extremely Low
Recommended Change Interval	3,000 - 5,000 Miles	5,000 - 7,500 Miles	Up to 25,000 Miles / 1 Year
