A Monograde Question

Not open for further replies.
Am I in the fan club? I just picked up two gallons of CD/SJ Kendall Super D-3 30wt from my grandmother's garage.

Maybe I'm in my own BITOG club, the "Run 20 Year Old Straight 30 Kendall Club".
 
Yep, you're in the club as my usual response for your home state members using 0w20 is "Run Forrest".

Edit/ is the Kendall Green?

Most of the stuff you see for sale in shops is aimed at the lawnmower market, you need to ask the rep about better oils. I'm using this 30 in one of my motorcycles, looks to be very similar specs to the Penrite 30.

However, contrary to popular opinion, modern GL-5s are yellow metal friendly, therefore can be used where brass/bronze/copper bushings are present. BP, Castrol here, might publish the copper strip pass results, 1-A being the best.
ASTM ... ?
Friction enhanced, in the case of TO-4s would be the opposite of a friction modified engine oil, and more like an automatic transmission fluid except in engine oil grades instead of ISO grades.
John Deere, Cat and others are very specific about wet clutch lock-up and fluid friction properties, anti-chatter braking and clutch pack life.
I like the idea of extra traction to help spin flat tappet lifters, and not so gaga about over the top ZDDP numbers as some other members might be.


Can't offhand see how that last bit (my bolding) would work with my flat tappets. Don't they inevitably follow the cam profile, at least on the up stroke? I suppose enhanced friction (adhesion?) could maybe make them follow it on the downstroke too, maybe reducing valve bounce, if that was an issue.

I can see how it might be relevant to roller cam followers because they, like, roll.

IIRC the bucket cam followers on pushrod engines are/were supposed to rotate around the pushrod axis (Its been a long time since I've had one in a car, though I did have a pushrod motorcycle until fairly recently) so maybe it works there too.

It's the type of friction modification that helps clutch packs and wet brakes work without slipping or being grabby...look at any HDMO with Allison C4, and it's the same concept.
 
No, it is medium amber. I think only the GT-1 was dyed green. I have a case and a half of that.

I need to post some pictures, maybe later today.

Right. A spinning hydraulic tappet. Don't see why not (in fact I don't see how it's original enough to be patentable, though I didn't read it properly yet) but I don't see that its relevant to MY flat tappets.

These are MY flat tappets. If those start spinning, whatever the oil, seems to me something is more than usually broken.

Count me in I guess - I'm currently running Valvoline VR1 SAE 40 in a liquid cooled wet clutch shared sump motorcycle. Bike loves it so far.

The product data sheet indicates that it meets API SN but on the bottle it only says 'Exceeds API Service SL'.
 
Red- your Kendall was made after 1976--cause it has the UPC--universal price coding--the bars & numbers scanned when making a purchase today

That Ford patent was the 1st one that came up that explained the friction reduction caused by spinning FT followers.
At the bottom of the patent, as in most cases, there are related patents that will keep you reading all night as one patent leads to the next until, your brain explodes from information overload.

or later, presumably, since you can buy CD/SJ (and SG, SF etc, though not certified as such) stuff today.

Think for pushrod bucket tappets I've seen it explained (probably sometime in the 70's) in terms of "spreading the load/wear" so you dont get a grooved tappet, but it isn't hard to see that dynamic friction would be lower than static if you've ever, say, shoved a sledge.

I always assumed rotation was achieved by having the cam slightly off centre on the tappet, but I dunno that for a fact.
 
I apologize for getting off track in this thread with the Kendall oil. I suppose I'm just excited.

I also wanted to say that we are very lucky to have members userfriendly, Shannow, and BrocLuno on the board. I've learned so much about the benefits of monogrades from you guys.
