Castrol Edge VS Amsoil OE

So, your conclusion is his conclusion is wrong? OR, You just like making fun of Kermit. 

 

All he really said was all Group III oils of the same viscosity with the same add package blended to the same specification or license do the same job no matter who's label is on the bottle. Specifically ILSAC GF-6 for SAE 5W30. 

 

If that ain't true, tell me and I'll buy an empty AMSOIL OE or Royal Purple bottle and pour some NAPA Gold into it before the next move to the motor. That's a magic bottle right there and worth the extra cash. SOLD!!! 

Show us the titanium trace Kermit!

Did he owe us that? It's his study, right. Perhaps his "intellectual property'. In any case, he gives us enough to make his point. Same oil gives the same performance. Point, set and match.

Thats what API wanted. So he proved what the industry already knew. Ok.

Yeah he did. He even mentions it but distracted the non science folks with BS distractors.

Okay, progress. It is what they wanted and achieved. Yes. And yet MARKETING keeps people ignorant and confused with claims of superior performance from the different labels of the same darn thing. Hoorah, Mobil got some solvency in a few cheap oils adding AN to a Group II/III blend that will not check the PAO boxes below. Havoline with some "Renewables". 

 

To get a superior lubricant you must use a truly superior base. Marketing 'claims' lesser bases are 'just as good' or nearly so. Not even close. Not even GTL/AN blends will check all the boxes below....

 

PAO

1.) Lower tractive force (friction) by over 10% which can be further lowered with a bit of POE or Diester if done right. 

2.) Higher Thermal Capacity and Transfer Rates. 10 to 20%. 

3.) Greater Oxidative resistance by about a third

4.) Higher natural VI. (apples to apples now) 

 

Those oils are not sold generally at Big Box outlets and not at $25 per five quart jugs. I've seen AMSOIL SS at Blains Farm and Fleet. 

 

AMSOIL SS and Euro, Red Line HP and HP Euro. Some HPL offerings, some Torco offerings, Some Ravoline offerings. Some MPT offerings. Some Gibbs Racing. PAO/POE blends. There are others if you turn over enough rocks.  But all of these blenders also offer Box Store Oils at a premium price they don't deserve. Some are transparent and some are not. I don't shop the bottom shelves at Red Line nor AMSOIL. 

 

You've mentioned a few times that no one needs a POE's thermal protection. Translated oxidation resistance and yet it's that quality that can permit SAFE extension of the OCI putting pressure on some other limit of condemnation.

Thanks but..............

Like I said before, Amsoil to me is better than off the shelf. Everything I have used it in I have seen improvements. Quieter motors, better shifts for transes, quieter transfer cases and differentials.

 

My new SXS is easy to hear changes in the drive line compared to a vehicle, no where near the sound blocking of a vehicle. The manual was 120 miles for first service, motor oil, trans and diffs. I did 80 miles with Amsoil ATV products.

With 80 miles still a tight drive train, I said before it was quieter. 

 

I used Amsoil small engine oil in my snowblower and I could tell the difference. Amsoil hydraulic fluid in my log splitter made it quieter. 

 

I know this isn't scientific but it's good enough for me.

My experience is the same. I don’t use it in everything anymore because I don’t do my own changes in most cases. I’ve documented many times the tens of thousands of dollars Amsoil has saved us in hydraulics and automatic transmissions. As far as engines, lower temperatures and oil pressure improvements while towing heavy.

My post was toward the OEM line of motor oils only. AMSOIL has many very good products and their gear oils are some of the best. Motorsport oils are quite different than the OEM line. This tread is based on that comparison, right?  A mineral based oil, Castrol to another mineral based oil, AMSOIL OEM, both of the same licenses and SAE grade. Apples to apples.

 

Perhaps not information you are interested in but you know me....

 

The OE line does not have a DEXOS LICENSE and there is a reason that makes that matter in explaining the 'quite' you experience. DEXOS1Gen2/3 is an 'energy conserving oil" so those with a license hug the basement in viscosity for their grade. OE is 'recommended for" and testing is done in "Comparison to" but it's specs are no where near the viscosity bottom which even when they have base oil 'type' read across and use the licensed add packages can not qualify as a Gen2/3 or ILSAC GF-6A fluid. Even thought the video testing did not bear out lower wear you will most certainly HEAR the difference. Same reason other Group III oils that meet C3 specs cannot meet GF-6 specs. Different minimum viscosity spec. (HTHS) different stability requirement. (SSI).  

 

But even give that, as a Group III product it cannot under any circumstances produce a Group IV result. Only a Group III result. @customboss and I both pointed out the test was short but the physics is long.

@Grumpy Bear @OnTheReel @diyer2@KARNUT@Black02Silverado among others can we match BITOG here without the market BS AT BITOG? You guys are SMART and EXPERIENCED.

There is an interesting article in Jan '25 edition of Lubes'n'Greases mag by Tom Glenn, Petroleum Trends International.  He cited an API report that stated nearly 50% of the engine-oils sampled failed to comply with licensing standards.  Leads one to wonder if the cheaper brands are playing fast and loose with additives to reduce the selling price?

Thanks, Tom is a friend, former lab rat like @Grumpy Bear and he’s always finding interesting things with cheapass oil brands. 
 

@Z45 you seem well informed. Do you have a fuel’s or lubes background?

Humans are like my dog Rex. He's really smart and listens really well. Until you say, "Squirrel"!  

 

BITOG is a hundred or more voices screaming, "Squirrel"! Humility does not come naturally to humans.

Exactly why we should have some adult supervision here and counter that stupidity there.  diyer2 and karnut would slam the " Squirrel" folks.

I come from folks that are direct and to the point. I believe in seeing results, not reading results. When you say what you’re doing results in a half a million miles. Ok where’s the beef? I only post experiences that I witnessed and participated in. I have 4 vehicles that have over 150K miles up to 23 years old. All with different oil and change intervals. I have family members that drive vehicles with over 200K miles and 20 years old and over. My mother drives a 2000 Ford diesel with 250K miles. She’s 86 and refuses a new one. Her other truck is a 98 Ram diesel. No one is going to tell me I’m doing something wrong in that department. I know what works.
