Lake Speed Junior High Zinc Oil new video

[LordNilesStandish]

LSJ has a new video out discussing 'high zinc oil' which he admits is partially his making.
He goes into many in depth aspects of these oils and gives a very interesting and informative narrative.

 

[Glenda W.]

My favorite part was him buying M1 TriSyn at Kmart for the Nascar race.

Interesting oil. Contains alkylated naphthalene like M1 EP and Truck and SUV do. Very shear stable, as expected given the relatively low VI in the low 140s. It might not contain any VIIs with such a VI. Indeed contains much more ZDDP than most typical API SP oils. His lab results for Zn and P are not in the right ratio for ZDDP (~1.1), being 1.18, indicating measurement error. What the tests could not determine are the type(s) of ZDDP used, which is also important.

Watch the final few minutes if you want to save time.

Good video. IMHO.

 

[Jetronic]

Yes noticed it too.

When I say the right 10W-30 can be a very interesting product, I mean stuff like this Mobil1.

I use a ravenol product with less ZDDP but more ester.

Good video in general. Did it come to a Yogi fork in the end - had much praise for the product and test results - then says old engines don’t need it - but will do some camshaft/lifter testing … Perhaps the video was a bit premature …

Don't some or most esters and ZDDP compete for surface bonding/adhesion? If so, would it be beneficial to have higher ZDDP in a higher ester oil?

I'm gonna use this oil in my Honda mower. Seems like a great power equipment option.

I was thinking that it might also make a decent cooler weather motorcycle oil, but then I saw the silicon/anti-foaming was on the lower side, so it might not be so great with wet clutch system.

the ester also keeps the zddp in suspension, and both are attracted by metal, it likely keeps the zddp close to the surface.

Additive packages have to be carefully balanced to do a variety of things.

Pablo coming around and watching a LSJ video???

I don’t idolize the guy and I don’t hate the guy. This video makes sense and really no different than BITOG 25 years summary

You will also note the length of his last 4-5 videos vs the length of videos in the past

How does LSJ test engine oils?
No API, ACEA or other governing body certifications or manufacturers’ tests or approvals. Just three pulls on a dyno with a 70 year old engine design with a ft camshaft followed by a UOA.
Thankfully nobody here is falling for it.

Power equipment engines have such low valve spring pressure it doesn’t matter.

Non standard testing

I think you maybe watched a different video?
In this video he undertook standard oil testing and analysed the results. There was not one single dyno pull.
He did say he wanted to run it on his test rig.
In a previous video he presented how he used a standardised proprietary in house test method developed with I think comp cams. This allowed him to compare flat tappet pushrod cam wear results for different oils under standardised testing. Ok it's not an ASTM test method but as long as all variables are standardised and controlled and undertaken using scientific method whats the problem? All the ASTM tests started as non ASTM test methods.

Comp Cams can measure wear down to a millionth of an inch. Flat tappet cams for NASCAR have welded lobes and use the Ford diameter .875” direct lube (Howard’s Cams) lifters.
In this application the lifters will fail before the camshaft lobes round off. The cam and lifters only have to last the race, maybe finishing on five cylinders.
Three dyno pulls with a small block Chev followed by a used oil analysis to determine the suitability of an engine oil for a specific application is absurd.

@Tom NJ had somewhere a great post ,i read ,explaining that.

I was thinking that it might also make a decent cooler weather motorcycle oil, but then I saw the silicon/anti-foaming was on the lower side, so it might not be so great with wet clutch system.

@Jetronic the one 10-30 he mentioned he uses, IS an oil like that
