Both are fully synthetic which makes the contenders highly efficient, performance boosters. Both contenders because of being synthetic rely less on additives, decrease downtime for maintenance and increase the life span of a device.
Both are 2-stroke engine oils extensively used in easy-to-use power devices due to their high power-to-weight ratio. Both are approved by API TC.
Saber is an excellent lubricant as it controls friction and helps avoid wear, plug mudding, ring sticking, and worn-out port blocking.
Its synthetic base oils ignite more easily as compared to other ordinary base oils.
It eradicates carbon deposits that lead to jammed piston rings. Mixing it at 100:1 halves the oil costs.
It delivers dominant results when it was tested for 100:1 against 50:1 other 2-stroke oils.
It still fights well against carbon deposits, a cause of reducing service life, when utilizing half of the oil.
Ultra has excellent engine cleaning properties.
Additionally, it has ultra-lubricating properties that are superior to other 2-cycle engine oils.
It is also extremely biodegradable, degrading up to 80% in 21 days.
It ensures enhanced engine protection as well.
In comparison to Saber, Ultra has better endurance in high-temperature conditions, consumes less fuel, and flows easily due to lower kinematic viscosity but lacks in a way that it’s slightly expensive, meets an inferior JASO standard and it is not a suitable choice for colder weather.

Features of Amsoil Saber;
- Provides additional fuel benefit by delivering a stable performance that helps to prevent fuel degradation during storage which affects the engine performance.
- It clears the industry-standard smoke test on a standard mixing ratio. When mixed at the SABER standard ratio, the smoke is almost eliminated or lowered.
- Provides fewer discharges at 80:1 and 100:1 fuel/oil mixing ratios.
- It delivers excellent lubricity and cleaning performance.
- Supplies exceptional shield and performance at a low mixing ratio.
- Reduces friction and wear, and prevents bad plug sparkling, ring sticking, and exhaust port obstruction.
- Improves controlling the flow of fuel or power to an engine.
- Reduces deposit development and reduces emissions.
- It is extremely endured to heat and stress to defend engines against wear and injurious deposits.
- Cost-effective and saves time while delivering vital accessibility and engine protection.
- Its synthetic base oil ensures clean burning as compared to other ordinary base oils.
- Mixing it at 100:1 halves the oil costs.
Feature of Stihl HP Ultra;
- It is chemically firm under normal storage conditions.
- It is highly bio-degradable, above 80% in 21 days.
- It ensures clean burning due to synthetic esters as lubricants
- It is environmentally compatible.
- It has a prolonged engine life due to wear additives and avoids clutching.
- It retains high efficiency for a long time.
- The low capability of carbonizing evades oil residues and deposits inside the engine which helps in preventing blocked valves.
- Due to its visual green color, the progress of mixing can be seen.
- It has ideal self-mixing properties.
JASO FB is defined to meet the great lubricity performance but lacks low-smoke and exhaust system obstructing technology.
JASO FD surpasses JASO FB as it has high detergency and engine cleaning performance as well as lubricity and low smoke requirements.
Both JASO FB and FD are suitable for 2T and small engines.
Both contenders follow the API TC standard that ensures regulation of lubricity, cleanliness, ash amount, and pre-burning.
Saber is better comparatively as it has superior JASO standards.

Endurance in Extreme Temperature
The minimum temperature at which a liquid maintains its pourable consistency, or in other words, it still works like fluid is called the pour point.
The lowest temperature at which the vapor of an igneous liquid will burn in the air is called the flash point.
It is usually lesser than the temperature required for the liquid itself to burn. The flashpoint of Ultra is comparatively higher and hence it will perform comparatively better and longer in high-temperature conditions.
The pour point of Saber is lower than its opponent which shows that it is a better option in cold weather conditions and hence will freeze later than its competitor.
Hence it is concluded from the observations, Ultra is a better choice in high-temperature conditions while its challenger has better temperature endurance in a colder environment.
|Parameter||Amsoil Saber||Stihl HP Ultra|
|Pour point||-40 °C||-39 °C|
|Flash point||180 °C||220 °C|
The resistance of a liquid to flow is called its viscosity which is affected the temperature variations.
And if we divide this viscosity by the liquid’s density, we would obtain the kinematic viscosity.
The higher the value of the kinematic viscosity, the thicker will be the fluid, and hence will become difficult to flow.
The kinematic viscosity of Ultra is relatively lower at both temperatures, so it will flow more easily than its contender and will devour less fuel to circulate.
The reliance of kinematic viscosity on temperature can be relatively compared and estimated by the viscosity index. It determines the variation in viscosity concerning temperature.
A higher value of the viscosity index indicates the least alterations in the value of kinematic viscosity.
As observed from the results, the viscosity index of Saber is relatively lower which means that it would be relatively quick to adapt to environmental change.
|Parameter||Amsoil Saber||Stihl HP Ultra|
|Viscosity at 40°C||107.4 mm2/s||46.0 – 52.0 mm2/s|
|Viscosity at 100°C||14.0 mm2/s||7.9 – 8.9 mm2/s|
|Viscosity index||131.3||142.8 – 151.2|
