Is Lucas gear oil gl4?
All Lucas gear oils are gl4 and gl5 approved..
Which is thicker 75w90 or 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 is the best 75w90 gear oil?
AMSOIL SEVERE GEAR® Synthetic SAE 75W-140 EP Gear Lube provides all the top performance of AMSOIL SEVERE GEAR® synthetic gear lubes for the heavier SAE 75W-140 viscosity recommended by many equipment manufacturers, especially those covering heavy-duty pickups and other high-stress equipment.
Can you use 75w140 instead of 75w90?
I think you’ve got your numbers backwards the 75W140 is the heavier (140 vs 90) and for more severe service. It is recommended only for the rear diff and only for heavy towing and continuous use. You shouldn’t go heavier than 75W90 in the front and for normal duty and occasional towing 75W90 is fine for the rear.
Can I use SAE 90 instead of 75w90?
Yes. 75w-90 should be just fine.
Can you use gl5 in place of gl4?
Modern “dual-rated” GL4/GL5 lubes for MT’s are completely safe.
Does Lucas gear oil have limited slip additive?
Formulated for limited slip and posi, no need for additional friction modifier. Holds up to the rigors of four wheeling, boat hauling, and the track.

Does Lucas Oil Stabilizer increase viscosity?
Yes. In fact, I think the term “stabilizer” comes from the fact that your oil pressure won’t go as low at idle when the engine is warm, so the oil pressure is more “stable.” In a worn engine, it will usually increase oil pressure throughout the rev range. You must log in or register to reply here.
What does GL 5 mean in gear oil?
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.
Is Lucas bad for your engine?
Maybe. Perhaps the right question should be “Does using Lucas Oil really protect your car engine from the wear caused by cold starts better than the factory specified oil?” Probably not. … With proper maintenance the factory recommended oil is good to use for at least 150,000 miles.
Can I use Lucas in my differential?
A: Yes, In addition to being great for your engine, you can also mix it 25% / 75% a manual transmission and 50% / 50% in the differential. Lucas Oil Stabilizer blends with any petroleum-based or synthetic oil, and is formulated for gasoline or diesel engines.
Should I use synthetic gear oil?
The benefits of synthetic oils relate to the molecules’ stable nature and include a higher degree of hydrolytic stability and demulsibility, a higher viscosity index (VI) and a lower pour point. … The VI and pour point allow these oils to perform better across a broader temperature range.
Can I use gl4 instead of gl3?
GL-4 will have more EP additives than GL-3. You can actually see that a substitute product on the list says GL-3 or later. GL-5 just can’t be used because the EP level is so high it degrades the copper alloy parts in the trans (aka syncros). The answer is racecar.
What is the thickest gear oil you can buy?
The SAE grading system indicates oil viscosity in simple numbers ranging from the thin oil (10) to the very thick oil (140 or above). Heavier weight, or higher grade oil is more viscous and therefore thicker as it flows between the gears. Light grade oil is ideal for small, fast, polished gears under a light load.
What does 85w 140 mean?
The first number of the designation specify the oil viscosity at cold temperature, the second number specifies the oil viscosity at high temperature. For example: SAE 85W-140 oil has a low temperature viscosity similar to that of SAE 85W, but it has a high temperature viscosity similar to that of SAE 140.

Can you mix gl4 and gl5 gear oil?
Note that the transmission lube is a GL4 while the differential lube is a GL5. You can use GL5 in the transmission, of course, but it is not necessary; the GL5 has Extreme Pressure additives, needed for the sliding action of the hypoid gears in the differential.
Is Lucas Oil Treatment good for your engine?
Lucas Oil Heavy-Duty Oil Stabilizer This Lucas Oil stabilizer is a reliable product that proves to be quite beneficial for old engines. It increases the oil life and reduces the overall oil consumption, maintaining the engine for a longer time.
Can you use 75w90 instead of 80w90?
SAE 80W-90 gear oils use mineral oil as a base, which means more frequent oil changes leading to increased maintenance time. … Synthetic-based SAE 75W-90 gear oils also prevent oxidation and oil thickening that mineral oils are susceptible to, and thus have longer life versus SAE 80W-90.
Which gear oil is thicker 80w 90 or 85w 140?
80w-90 front, 75w-140 rear. Rear gets more of a workout so more heat. This equates to thicker lubricant.
