GHS Statement​	For commercial and professional use only
Beneficial Qualities​	Performance Features 100% synthetic oil with proprietary additive package Exhibits low volatility and low viscosity shear characteristics Provides excellent low- and hightemperature performance Exceeds performance criteria of API and most OEMs Outperforms commercially available passenger car engine oils Protection Mitigates wear in Low-Speed Pre-Ignition (LSPI) conditions Increases gasoline engine reliability by reducing wear Features low-temperature flow characteristics to ensure continuous flow of oil film Isolates metal from rust and corrosion Provides superior oxidation protection Prevents formation of ash and other deposits, even in highly problematic areas such as ring zones Protects from higher temperatures found in engines with turbochargers and superchargers Provides superior wear protection during start-up and idle Endurance Safely extends drain intervals when combined with LE’s Xamine™ oil analysis program Extends oil service life Extends engine life Efficiency Exceeds “Resource Conserving” guidelines for API SP engine oils Improves fuel economy in many newer engine configurations Lowers emissions and protects emission systems per API standards Is suitable for use with ethanol-containing gasoline up to E85
Proprietary Additive​	LE’s proprietary additives are used exclusively in LE lubricants. Monolec® Syn Engine Oil contains Monolec. Monolec® wear-reducing additive creates a single molecular lubricating film on metal surfaces, vastly increasing oil film strength without affecting clearances. An invaluable component in LE’s engine oils, industrial oils and many of its other lubricants, Monolec allows opposing surfaces to slide by one another, greatly reducing friction, heat and wear.
Performance Requirements Met or Exceeded​	API SP Resource Conserving/SN Plus/ SN/SM/SL/SJ Chrysler MS-6395 Ford WSS-M2C946-B1 (8531), WSS-M2C945-B1 (8521), WSS-M2C947-B1 (8511) GM dexos1™: Gen 2, 6094M (obsolete), 4718M (obsolete) ILSAC GF-6A
Typical Applications​	Personal passenger cars Passenger car fleets (municipal, delivery, etc.) Offers exceptional performance suitable for use in most OEM gasoline engines, including Honda, Ford, GM, Toyota, Chrysler, Nissan and Hyundai/Kia. Consult your owner’s manual for details.

No, I think there are better oils out there. I would pass on this Oil.

 

[JavierH19]

2.8 hths? that's the lowest I've seen for a 5w-30. I know valvoline and i think quaker state is 3.1 for their 5w-30 and the 10w-30 is 3.2. It meets sp and has the easy approvals like d1 g2. I would not pay more for this than supertech. If they ask for more I'd pass.

Yeah a 30 grade with sub-3.0 HTHS? Hard pass, must be absolutely loaded with VIIs. HPL has a 20 grade with 3.26 HTHS…

Years ago, some auto makers supposedly used oil from Lubrication Engineers for their EPA MPG testing if I remember right.

I agree on the sub-3.0 HTHS for a 5w-30!

Which HPL 20 grade has the 3.26 HTHS?

 

[Glenda W.]

Exceeds “resource conserving” no thanks

 

[Bailes1992]

Exceeds “resource conserving” no thanks

That just means it's super resource conserving! What's not to like?

No VII Euro 5w20

I normally select a viscosity grade and look at the Performance Requirements section that for example you have listed and ignore the rest. Then you know at a minimum what you are getting! The rest can give you a headache like thin 30, thick 20, solid 40. If I'm concerned with that, I buy one grade thicker.

Also it gets tricky if the oil has the approvals or meets or exceeds ... So with unknown (to me) companies, I am much more cautious!

Having said that, I like the color!

That’s essentially an API SP oil. There are lots of those at Walmart for a good price.

 

[Patman]

My memory might be a little fuzzy on this one but wasn’t the LE line of oils considered to be one of the top boutique oils on here a few years ago?

Not sure if it was or is a boutique oil. LE is a well known formulator focused mainly on industry. I’ve been using their products for years and I’m happy with them. I use their conventional Diesel oil in my PSD and oil consumption dropped markedly compared to the Mobil 1 Turbo Diesel oil I had been using. It was not cheap but considering that I no longer have to add oil between changes it costs less than the Mobil 1.

I think they know what they are doing and if the HTHS is low on the specific product in question here there is a reason for it and engine wear will not be a problem.

What you think and what they claim do not alter the physics of the issue. If the HT/HS is low, especially below 2.7, wear will be significantly higher than oils with higher HT/HS. A 30 grade with an HT/HS will suffer much higher wear rates than a 30 grade with an HT/HS of 3.2 or higher. The end.

Brand doesn’t trump physics.

Sorry friend, never heard of it.

Are you thinking of Renewable Lubricants? When i read the title i did for a second.

What you think and what they claim do not alter the physics of the issue. If the HT/HS is low, especially below 2.7, wear will be significantly higher than oils with higher HT/HS. A 30 grade with an HT/HS will suffer much higher wear rates than a 30 grade with an HT/HS of 3.2 or higher. The end.

I emailed LE asking about the issue of the low HTHS result. They did not bother to answer.

This is one of the reasons I pick HPL- generally speaking they not only disclose more info than most oil companies, they also respond to questions in a timely manner. To me, no response at all says that company’s got something to hide.

Nobody ever gets “all” the info we would like (due to IP, etc.) but I’m unaware of anyone who has contacted HPL being disappointed by the results of whatever oil was recommended.

My opinion only.

 

[4WD]

Hmm, assumptions and bias. There are lonely SP HD-SAE30’s that can still protect if the climate/engine is right … OCI fits …
