Is 80w90 the same as 75w90?
80w90 is the best oil for winter and summer weather conditions. 80w90 has a higher rating than 75w90 due to its tolerance to both cold and hot conditions. But 75w90 is limited to higher temperatures to minimize premature wear and tear. The winner under this category is 80w90 gear oil.
What is the viscosity of gear oil?
The main thing you’ll notice about gear oil is its viscosity. It’s much thicker than motor oil, with an average motor oil being 5W/30 and the average gear oil being 75/90 (see this article for in depth explanation of oil viscosity index).
What is the difference between 75W and 80W gear oil?
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.
Can you substitute 75w90 for 80w90?
Ans: Yes, you can mix 75w90 with 80w90.
What does ISO mean in gear oil?
International Standards Organization Viscosity Grade
ISO VG stands for “International Standards Organization Viscosity Grade” and is reported in numbers ranging from 2 all the way up to 1500. This number is critical because a lubricant’s viscosity is the single most important factor when selecting the right oil for your machinery.
Can I use 80w90 instead of 75w90 gear oil?
The oil weight is not a noticeable difference, most if not all 75w90’s are synthetic or synthetic blends. 80w90’s are dino oil. I would think your oil change interval would be reduced by half, so 50k miles instead of 100k. 80w90 should be safe to use, and you won’t notice a difference.
What happens if gearbox oil is too thick?
Too thick and excess drag is caused, reducing economy and sapping power. Gear oil is either rated as either a single grade or a multi grade oil. A single grade oil will have a rating such as SAE 90, and a multi grade oil will have a rating such as 80W-90.
What happens if you use the wrong gearbox oil?
Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.
Is 75w-80 MTF gear oil correct for my car?
Even if your vehicle manufacture states it’s fill for life, you’ll quite often find it still has a drain an replacement time scale… so well worth checking If you’re in any doubt if a 75w-80 MTF gear oil is correct for your car then you’ll normally find the correct spec stated in your owners hand book.
What is the recommended gear oil viscosity for my application?
Satisfies the gear oil viscosity requirements of 75W, 80W and motor oil viscosities of SAE 30, 10W30 and 5W30 Recommended for GL-1, GL-3 and GL-4 applications as well as where most special synchromesh fluids are specified
