oil pump

[Wietse]

Yesterday i spoke with my engine builder as well about oil, he recommended to continue using the Kendall oil.
He and friends of him use it as well for the stock car race engines and never had any problems.
Looking at the condition of my camshaft i guess the oil is good for these engines, ZDDP level is good.

Being a sceptical person, I have to ask WHY he is recommending Kendall oil ..... is it the additive package, or a specific viscosity index or the price he purchases it for or the color of the can.....or what? You mentioned "problems"... like what....spun bearings due to film strength break down or cam/lifter failure due to scuffing...be specific not generalities....its difficult to draw conclusions based "guesses". BTW, ZDDP levels are measured in parts per million or grams per litre or some level beside "good".
Kendall Refining Company used to be Pennsylvania (Oil City) based, using Pennsylvania sweet crude oil as the base stock which was reputed to have a high paraffin content with low ash and sulfur components. Today, oils are made from a large variety of base stocks and can be reformulated to just about any combination of molecules including natural gas (Mobil One and other synthetic derivatives). Has your engine builder used/tried other oils? Which ones? Quaker State Oil and Refining and Pennzoil Refining Company all were Pennsylvania based oil refining companies also...does that make their products as "good" as Kendall's offerings? Inquiring minds want to know.....
It all comes down to performance (first) and price (second) and availability (third) as to which lubricant is best.

Will see what the new pump will do.
The Kendall racing green oil is getting more and more difficult to get here so i might have to swap anyway to something else as 10W40 or so.

Edit: Like this stuff, i asked the manufacturer before about the ZDDP content....but that was classified information

The original Kendall formula was continued by Brad Penn. Then Brad Penn was bought by Penn Grade. It's the original "Green" formula that's been in existence for fifty years. So any Brad Penn that's left out there is good to purchase or just get the latest Penn Grade. Summit sells it.

I started out with the Brad Penn 30w break in oil then went to Penn Grade 10w 30w partial synthetic. They are formulated with the original zddp content for flat tappet cams.

The "name" changed during my break in and I was concerned about what was going on. I contacted Penn Grade and spoke with their head chemist. He assured me the name changed was just that and the original formula was still the same as what it was when Kendall had it.

Also I can't stress it enough, zddp additives are just for oil that doesn't contain any. Adding it to oils that already have it can have different results than what the original formula was designed for.

Being sceptical is ok i guess, but why question someone who has been using it for years and never had any issues with damaged bearings or worn camshafts?
It is obviously a mix of the additives that are to be there for engines with flat tappet cams, the right viscosity for it's purpose, etc.
I know that ZDDP is indicated by PPM, and flat tappets cam manufacturers recommend a certain minimum of PPM zinc content.
IIRC the Kendall Racing Green oil had 1200 PPM ZDDP content.
I am not making any statements here about this oil is the best, or anyone should be using this, use whatever suits you but as i found that i am using the same oil as more professionals than me for an not-standard engine gives me more confidence in continue using it.

The Penngrade1 website's advertisement for their product is nice and, as expected, to be biased to their products and benefit. Perhaps they should compare their ASTM references (and the other testing references noted) with the other market place lubricant suppliers' testing results. That way the playing field is uniform for the end user is free to make his own decision based on actual data presented. Years ago, a product called Bardall, was marketed as a product that was added to the oil to eliminate friction on bearing surfaces. It was heavily advertised....did it do what was claimed??? Some people claimed that it did....some people did not...who is right?
Does the "geen color" make it a better lubricant? Remember back to Royal Triton lubricants, which were colored a Royal Purple color...did that make it a better lubricant ? Perhaps you can share the name of the chief chemist you spoke with at Penn Grade lubricants, as I would like to pose a few questions to him. Personally, I like to do my own due diligence and seldom take someone's else's uneducated guess or preferences based on feeling or hearsay. It comes down to: "you pay your money and take your choice".....based on actual published data or seat of the pants methodology. Just my opinion of course.

FFS man, it's just oil.
If someone recommends you some brand of oil that meets the required specifications for your application you can go ahead and use it.
Offcourse every manufacturer praises their products sky high, but do you really think that any brand laboratory that tests their products have different findings on certain additives then other brands?
Every manufacturer knows what to add and what it does, it is the end user to take a pick between all the advertisement **** about how good every product is.
Select a viscosity and type (synthetic/mineral/blend), know if your car needs certain additives (as with these engines ZDDP is important) and check the standards meet the recommended specs as per car manufacturer.
Other things as operating temperatures etc. is also depending on application like street or race and come down to the end user to determine what is suitable.
Getting in contact with brand chemists is no help as they will tell you nothing about their blends and receipies as it is confidential information.

Skip the website and call them directly 1-800-645-5823 ask for Ken.

Loose the lab coat and speak english. You've been an engineer too long.

Thank you for the contact name and number....perhaps I'll take you up on the offer and ring him up. Been an Engineer too long???? I don't think so...for I'm always learning about cars, their performance attributes , life, and more importantly about people and what makes them "tick". Regards,
