Re: Oil debate numbers
Greasing that car is the worst job. I did it while I was in Oregon. I'm hoping the modern greases are better. Must be as they now make tie rod ends and ball joints without fittings.

Re: Oil debate numbers
Frank,
I used to work for a fleet and we did the oil reports on everything we serviced. Saved them tons of money over the years. We had everything from Police cars to lawn mowers. More than once they called and said you better get Car 12 in and have a look. Even the back hoes were saved more than once. Interesting to see it used on a flathead older car. keep the thread going... We used Kendall oil and the reports were provided at no cost.... |

Re: Oil debate numbers
I was surprised to see 900 ppm on the zinc, considering I have never used any additive. Low metals means my tappet are not coming apart.

Re: Oil debate numbers
This report is a few years old and I posted it several times but
this has information we should all know about oil. I have several small diesel cars and trucks and find the Cummins Blue 20/40, the number one oil perfect for my diesels. I like the quality of the base oil and the additives. I also use it in a few flatheads that I drove long and hard. G.M.

I changed it mostly because it had been in there a little over a year, but the analysis shows it was in fine shape.

Re: Oil debate numbers
Looks like we found something that works. Now to try using some cheap regular oil and getting the same results. Funny the oil did not wear out after a year either.

Re: Oil debate numbers
Good thought, Frank.
I am going to have the oil tested in my Mazda Miata at its regular oil change interval. I want to test the oil in both of my Model A's, too. I use Mobil 1 in all of them. |

Re: Oil debate numbers
Thanks to Frank and Ross for sharing these results, and congratulations on having seemingly sound engines. Both of these reports had at least the majority of the mileage accumulated on trips. I would venture that most of us don't have mostly long trip/highway miles on an oil change. My engine is soon coming up on 2000 since rebuild, with 1500 on this 10w30 Motorcraft oil. I plan to change it soon and already have the Blackstone kit.
I think it interesting that both Frank and Ross have the bypass filters and both got excellent test results. |

No doubt the most important thing, IMO, is to start with a clean engine. Even the best oil can't overcome years of sludge contamination.

Re: Oil debate numbers
Frank, I use Shell Rotella T 15w40 in my flathead engines. I could send a sample in on my next oil change. It's not "cheap" oil but also not synthetic.

Re: Oil debate numbers

Re: Oil debate numbers
All the lube and oil change recommendations were for more dirt roads than we drive on today. A Model T had no oil filter or air filter. Those old T's and A's sucked a lot of dirt through those engines.

Re: Oil debate numbers
Ross F! You can have a filter dissected to determine what it is removing from the oil. The fact that there is not a lot of metals in the oil tells us there is no wear or the filter is doing it's job. If you go on Blackstone and read their newsletters there is a Ford overhead cam motor that was showing high numbers on the aluminum. This is a full flow system. Long story short it turned out to be a cam tensioner gone south and the chain hitting the aluminum housing. It was found and fixed before catastrophic results. For clarification this was just a result of a standard oil test, no filter analysis.
Thanks everyone for weighing in. This has been one of the more meaningful oil discussions on here because we have data not marketing hype. Ross and I used no extra additives and there is no indication of our cam and lifters being destroyed.

Re: Oil debate numbers
I think another fact that stands out is that both of you are using the stock by-pass oil filter system and your engines seem to be exceptionally clean.

Re: Oil debate numbers
Yes that is interesting, isn't it? I also assume that Walmart is having one of the major engine oil manufacturer's package oil under the Walmart name brand. I wonder if you can get Sam's Choice oil at Sam's Club? I suppose if it's available it would be in 55 gallon drums (I jest of course).

Re: Oil debate numbers
I got a reply from Blackstone about measuring filter effectiveness:
"Hi there, Ross Insolubles would be a good measure of how effective filtration is. Those are solids that accumulate with heat/use and it's the filter's job to keep them to a minumum. 0.2% is a pretty nice reading in that regard. I hope this helps but let me know if you have any more questions. All the best, Christopher Peden Blackstone Labs"
