What does GL-5 gear oil mean?
Extreme Pressure
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.
What is 75W90 gear oil used for?
The 75W-90 gear oil is used under extreme pressure conditions and is recommended for limited-slip differentials and for use in colder climates. Used in heavy duty manual transmissions, final drives and axles, high temperatures will not effect the heavy film left by this oil.
What is the difference between GL3 and GL5 gear oil?
GL3/GL5 Gear Oil Ratings GL5 gear oils can attack the yellow metals found in manual transmissions. GL5 gear oils are recommended for differentials. GL3 is safe for the yellow metals, and should be used in transmissions. GL3 fluids should not be used in the differentials.
Can you use GL5 in place of GL4?
The main difference between GL-4 and GL-5 gear oils is the amount of EP additives. GL-4 is suitable for hypoid gear service when they are under severe service but are without shock loading. GL-5 is suitable for hypoid gear service under severe service and shock loads and not for use in a gearbox.
What’s the difference between 75 90 and 80W 90 gear oil?
SAE 80W-90 gear oils use mineral oil as a base, which means more frequent oil changes leading to increased maintenance time. SAE 75W-90 maintains a more consistent thickness, or viscosity, across a wide temperature range. It’s thicker when exposed to high heat and thinner under colder, wintry conditions than 80W-90.
Is GL-5 a hypoid?
Gear Oil GL-5 delivers value through: Good gear life — Extreme pressure properties protect hypoid and other types of gears from scuffing and wear. The sulfur-phosphorus extreme pressure additives in Gear Oil GL-5 provide good gear protection in general gear applications.
Can I use 80W 90 instead of 75W90?
SAE 75W-90 maintains a more consistent thickness, or viscosity, across a wide temperature range. It’s thicker when exposed to high heat and thinner under colder, wintry conditions than 80W-90. The use of 75W-90 gear oil is recognized by OEMs as a contributor to overall fuel economy.
What kind of oil is in 80w90 GL-5?
Lubricant The oil known as 80W-90 GL-5 is a lubricant for the gears in your vehicle. The numbers “80W-90” refer to the viscosity grades of the oil. The label “GL-5” defines how much sulpher-based friction modifier is present in the oil.
When do you use 75W 90 gear oil?
What’s the difference between GL 4 and GL 5 gear oils?
The main difference between GL-4 and GL-5 gear oils is the amount of EP additives. Sulphur/Phosphorus containing products are used as EP-additive. This additive has the purpose to prevent the occurrence of micro-welds on the gear flanks at the local high temperatures which prevail in EP circumstances (temperatures well in excess of 800℃!)
What kind of oil is Penrite PRO GEAR 75w-90?
Pro Gear 75W-90 is a premium full synthetic, SAE 75W-90, heavy duty gear oil that uses a special combination of synthetic base oils which include PAO and Ester, with an advanced additive system to provide ultimate performance and protection under all operating conditions.
Which is fully synthetic gear oil ( SAE ) 75w-90?
Fully Synthetic Gear Oil (GL5) SAE 75W-90 Our fully synthetic gear oil is a high-performance, high-pressure gear oil for high-load manual, auxiliary, transaxle and hypoid transmissions which require a lubricant according to API GL 5. High-quality, fully synthetic base oils and modern additive tec +49 731 1420-0
What does fully synthetic gear oil ( GL5 ) do?
Ensures exact friction behavior and provides outstanding ageing resistance. Even under the most difficult conditions and during large temperature fluctuations, it ensures flawless aggregate functioning. Greatest lubrication security, maximum wear protection through large viscosity bandwidth. Facilitates easy shifting and smoothest running.
Which is VP 75W / 90 gear oil to use?
VP’s branded synthetic 75W/90 gear oil is getting hard to find in my town and very expensive as well. I have looked, read, and researched an alternative brand with the same specification but I have not gotten that warm and fuzzy feeling about which brand to use and what if any problems I may encounter in changing over.
What kind of lubricant is Lucas 75W 90?
360° Product View. Lucas SAE 75W-90 Synthetic Gear Oil is a non-foaming, super slick, long lasting lubricant designed especially for heavy duty or high performance applications where other gear lubricants just aren’t good enough.
