What does GL-5 mean in gear oil?

What does GL-5 mean in gear oil?

API GL-5 – Intended for heavily loaded gear sets with high sliding forces such as hypoid differentials. GL-5 lubricants contain high levels of extreme-pressure additives to provide protection under boundary lubrication conditions.

Is gl5 gear oil for limited slip?

PennGrade 1® Limited Slip GL-5 SAE 80W-90 Gear Oil is a specifically developed friction modified lubricant for clutch-type, limited slip differentials, reducing stick-slip ‘chatter’ in low speed high torque operations.

What does GL stand for in gear oil?

GEAR LUBRICANT
GL is short for ” GEAR LUBRICANT” API has the following GL classifications: for Gear Oils – GL-1: Oil without EP additive. GL-2: Usually contains fatty materials. GL-3: Contains a mild EP additive.

Is 80w90 thicker than 75w90?

80w90 is denser than 75w90. Denser oils like 80w90 can work well in high temperatures, but on the other hand, thinner oils like 75w90 are good overall, and they provide adequate gear protection.

What is the difference between hypoid gear oil and regular gear oil?

Hypoid Oil Differences It’s a gearbox oil, just like others, but the ingredients are different. This type of gear oil is mixed with additives designed to increase its resistance to breakdown under high temperature and mechanical pressure produced by hypoid gearboxes.

What lubricant is used in gearboxes?

Oil splash lubrication is often used for helical, spur, and bevel gearboxes. This method is also referred to as an oil bath, because it uses a reservoir is filled (or partially filled) with oil. As the gears rotate, they dip into this oil bath and splash the oil onto the other gears and bearings.

Can I put gear oil in my automatic transmission?

Whilst some manual gearboxes do use transmission fluids in place of gear oil, the same cannot be said for putting gear oil into an automatic transmission. Gear oil is much too viscous for these systems and will cause clogging between components.
