What is the difference between marine gear oil and regular gear oil?
Marine gear lube, unlike automotive gear lube, is formulated to emulsify water. This serves two purposes: It provides consistent lubrication, keeping water away from moving parts. It keeps the lower unit from freezing (yours didn’t freeze last winter, did it?)
Can I use 80W90 instead of SAE 80?
Yes it is the same… close enough anyway. SAE 90 gear oil is equivalent to 50wt engine oil (SAE 80 = 30wt), so you could always dump that in instead if you want.
What kind of oil do you put in a lower unit of a boat?
You can use any brand of lubricant that has a grade designation of API GL5 SAE 80 or 90 weight. Make sure you do not mix different oil brands or weights. into the BOTTOM drain hole. Then slowly squeeze the bottle to force the oil into the lower unit.
What is 80W90 gear oil used for?
Application. Gear Oil 80W-90 is designed for use in differentials, both hypoid and limited slip, manual gearboxes, transfer cases and transaxles in passenger cars, light commercials, 4WDs, trucks, construction, earthmoving and agricultural equipment, where this viscosity grade is required.
Can you mix Marine gear oil?
Important Note: Different gear oils cannot be combined. Each gear oil brand formula is unique; mixing two brands will result in a lubricant that is inferior to either of the two that you started with.
What does GL 5 mean in gear oil?
A GL-5 grade oil has a very high rating for EP (Extreme Pressure) protection. EP gear oils contain additives that prevent metal surfaces from cold welding under the extreme pressure conditions found in situations where boundary lubrication prevails. This is normal and acceptable in all steel gears.
Can you use 80W90 instead of 75w90?
Ans: Yes, you can mix 75w90 with 80w90.
Is 80W90 the same as ep90?
80W90 is a multiviscosity version of the single-viscosity 90 gear oil; it’s the same concept as 10W30 motor oil being the multiviscosity version of single-viscosity 30-weight motor oil. The “W” is a “winter” rating, meaning that the oil in question is designed to be usable in winter months in cold climates.
What does LS mean on gear oil?
Quality Additives. L S ENERGY SAVER GEAR OIL has incorporated in it a proven extreme pressure gear additive package and a friction modifier system. L S ENERGY SAVER GEAR OIL is formulated to offer enhanced lubricity and limited slip performance. In fact the L S in the name of the product stands for ” Limited Slip.”
Can you fill lower unit oil from top?
Filling from the top down will not allow all the air to escape from the gear box The heavy gear lube will stop flowing down as cohesion from surfaces slow it down till it stops as the air wants to go out the top hole If you let it sit overnight all the trapped air would eventually make its way up to the top
How often should oil be changed on a boat engine?
Frequency. Most engine manufacturers recommend that you change your oil every 50-100 hours (check your owner’s manual for your engine’s exact interval requirements).
What is the difference between 80W90 and 85W140 gear oil?
The viscosity chart rates the 80W90 up to 95 degrees while the 85W140 is rated up to 120 degrees.
What is the difference between 75W90 and 75W140?
So, the difference between “75W90” and “75W140” is that at operating temperature, the 75W140 will be considerably thicker than the 75W90 but at room temperature they will be about the same viscosity.
What does GL 4 mean in gear oil?
GL-4. Active. The designation API GL-4 denotes lubricants intended for axles with spiral bevel gears operating under moderate to severe conditions of speed and load or axles with hypoid (see note)gears operating under moderate speeds and loads.
