Lucas Magnum Synthetic 15w40 CJ-4

[CleverUserName]

Tried searching, couldn't find anything.

Has anybody tried this stuff before? https://lucasoil.com/pdf/TDS_15W-40-Syn-CJ-4.pdf

VI is 195 !?! That's crazy for a 15w40. Honestly, it's kinda hard to believe.

Do they put any specific esters in it too get it that high, or are they just putting a ton of VII in a group I or II

Seeing M1 0w40 is 186 I don't believe it either.

Typo.

It's a Lucas product. What do you think? I doubt Lucas knows what an ester is, much less put it in their product.
The only think listed on the MSDS is a 1 to 5% concentration of Phosphorodithioic acid, O,O-di-C1-14-alkyl esters, zinc salts.
Most blenders will list an ester if it's got it. They won't even list the base oil!
This stuff is 17.00 a gallon at Rural King. It's possible it's half Lucas stabilizer and half used hydraulic oil. Maybe....
(I'd still take the 12.99 for 2 gallons of Harvest King over it.)

Lucas 20w50 was shown to be pretty poor stuff, i wouldn't trust it.

Lucas products suck. Overpriced trash.

It must be multiple typos. I plugged the cSt values @ 40c and 100c into the Widman VI calculator and the value came back to the as-listed 195.

So they are totally fudging all their advertised specs or this stuff is potentially the most bada$$, best synthetic 15w40 out there...

Lucas professional racing oils are good, most all consumer stuff is below average to ... Nahhh!
