Amsoil for engine oil

Thanks.

 

Thank you!

Thanks @Pablo8 for your help! I placed an Order: 40901832

I mentioned your reference number in the Special Instructions so that they can add you as my dealer.

 

Hey @Pablo8 - My gear installer is recommending 75W-140 or 85W-140 after the break in of my 5.29 gears. What are your views on that?

 

You really don't need 140. 110 will be fine. Toss up. Hot desert 140. cool ocean and north and mountains 110.

BUT is 140 some kind of WRITTEN warranty requirement?

 

Good point! I will check with them. But as far as I understand it's a recommendation.

 

I've used M1, Valvoline, Penzoil, and Kirkland, i typically change around 5-7500 depending on my availability and weather, but i can't tell a lick of a difference...I don't plan to keep this till 400k anyways so im not sure its gonna matter...

 

Hey @Pablo8 I checked with the Gear installers, they are recommending 75W-140 for both front and rear diffs for their warranty. What would be difference between

$29 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75W-90 and 75W-140 at below freezing temperatures? Would the 140 become too thick and cause any kind of issues/binding? I understand that at operating temp the two have the same viscosity and at very high temperatures the 140 operates better. But I am concerned about cold weather performance of the 140.

 

Recommending or requiring? Important.

Yes 75W-140 is just too viscous for the front in cold temps. It does not need it for loading, hot or cold.

The rear, yeah in CA, probably not a huge deal to use 75W-140. Not a problem 99% of the time.

The problems with to high viscosity = oil starvation to the BEARINGS in the cold, and running even HOTTER in the high temps because of fluid friction heat and slower heat dissipation.

I guess the versatility of synthetic, you could get away with 75W-140...............but man you don't need it, and not sure they know their stuff all that great. I say this not to throw stones, but rather to use proven science.

 

“Requiring”. They won’t warranty it otherwise. They mentioned that they have had customers from Washington use the 75W-140 with no problems in cold weather. They also said that they put 85W-140 (non-synthetic) in the diffs right now for the break in. They would warranty it for 10yrs provided that I use this gear oil ‍

 

Then you must use 75W-140.

No choice if you want their warranty.

Doesn't matter what I say now. Right, wong, smith or pablo.

 

Totally agree with what others say. Amsoil is the best without a doubt. The price is the only factor before I pull the trigger. For the engine of Tacoma, it is not picky. Just use whatever is on sale full synthetic. Just my choice.

 

The 140 doesn't even come into play in cold temps. That what the "w" stands for (winter). So, in the cold, the 75 will be the number to look at. The 140 only factors in at high temps and means it won't turn to water-thin when the temps climb.


{Actually, because Amsoil is pure synthetic ---- i.e. will still pour at -45F (that's 45 degrees below zero) and will not flash over until it reaches above +410F ---- the viscosity numbers are pretty much just there for the consumer to feel comfortable knowing that he is buying what he thinks he needs. This stuff will perform (and out-perform everything else) in almost all temperatures and conditions found in the U.S. (90% of the rest of the world).}

 

Yea I was reading this and wondering wtf too...

Way too much thought being put into this.

This thread is from 2018 and ANOTHER oil thread, here is the 5.29 thread
5.29 thread where you can get plenty of info on what gear oil to use

 

Actually incorrect.
Pour point can be a bit misleading. The gear oil might pour, but still too viscous for bearings. The 140 will be more viscous at ALL temperatures than the 90 and 110.

Look at the -40°C viscosity.

Straight off I want you to know that I'm not trying to butt heads with you Paul. I like what you do for the Tacoma community! Keep at it.

Yes 140 will be more viscous than 90 & 110 at the lower temps, that's true. But not enough that a Tacoma in the U.S. would notice it. Not in syn oil anyway, but it absolutely would make a diff in petro oil!
Still, I can't argue the nitty-gritty facts of 90, 110, & 140 each having different viscosities.
And I wouldn't recommend using any product close to it's pour point. A limit is a limit, but even getting close to those limits can get exciting. However, I did just that in real life. I drove/used my vehicle in MN at -60F, running Amsoil (exclusively) and the car did very well! (That day in particular the windchill was -75F. Governor shutdown the state. Coldest on record. I was there and so was Amsoil. ) Other years I even ran 30w-50 diesel oil in my '83 Oldsmobile Cutlass in MN winters without issue. (yeah it was a diesel)

I simply wanted to say that the pour & flashover numbers are a great indication of the huge range that Amsoil will work properly at. In fact this 75w-140 even delivers 20 percent more cold-temperature protection than the standard (to earn those numbers) requires. So Paul, do recommend the proper viscosity ranges for your clients, I don't want to say otherwise, but know that a little deviation, when using Amsoil, won't make a bit of difference.

 

I had no idea that Amsoil was a multi level marketing model. If those who are pushing this product paid a sign up fee for the privilege of being an Amsoil rep and they get bonuses for signing up other reps, then it is indeed a pyramid scheme cloked in a MLM wrapper.

 

Yeah, maybe for a 700 hp engine that gets a lot of abuse, but for normal 3.5 tacoma most synthetic 0-20w oils will be just fine.

 

It is and I did.
But in 1979 it was the only API certified synthetic oil on the market and I wanted to use synthetic. So I signed on. Not to make money, but to get access to the oil at a discount.

For 42 years I've used only Amsoil in everything requiring lube (vehicles, mowers, weapons, bicycles, boats, weedeaters, etc.) and have never looked back. It still outperforms any other brand.

 

Right now, they put 85W-140 in my diffs during the break in process and I can tell you that on a chilly morning I felt like my truck was dragging the rear like it had a flat tire or something!

 

I’ve done each oil change on mine with Amazon Basics 0w-20 and oem filter. Why pay more for the same rebranded M1 or whoever makes it?
