1929 Model A Ford Oil Change and Analysis

Time to change the oil on the Sport Coupe

Air jack saving time and effort once again, you can see them here at Vevor

Was using a Mann filter on the Mike’s oil filter kit, article here on fitting the kit

Moved to the Bosch filter purely on a cost basis, these filters are a version of the Ford EFL90 used on the Pinto engine

Once the oil change was completed decided to inspect the oil and filter as the babbitt engine, (if the original), is over 90 years old and not the quietest!

Starting with a magnetic search in the drain bowl which came up all clear, followed this with the microwave test. This involves taking a small sample of oil in a container and running the microwave to see if any sparks result from metal present in the oil. Again all seems to be clear.

Next operation was to split the oil filter canister, didn’t make the best job of this part and introduced a little bit of metal and paint around the top edge. Wasn’t terribly worried as the folds are where the interest lies and this isn’t exactly scientific.

Once apart and fanned out found it to be pretty much clear with the exception of the expected small amount of sludge. SAE40 is the lubricant used and is a non detergent. The oil pan and pump were desludged not long after purchase. Past oil pan adventures can be found here. To help matters the oil filter kit and regular oil changes have been instrumental in keeping things clean.

So to sum up, perhaps a few more years left in the current lump (touch wood!)

It’s not just “golden-clear = clean” and “dark-opaque = dirty.” Motor oil is a complex, highly-engineered fluid before it’s even poured out of the container. And after it has been sprayed, dripped, and sloshed around in a running engine for a period of time, coming into contact with multiple materials and wearing surfaces, it holds the secrets of that engine’s overall health. There’s real science behind determining what the chemical and physical composition that oil can tell us. To learn more about this, and share it with you, we’ve tagged along with an enthusiast owner as he explores a new-to-him old-car purchase.

Case study:

Rodney Kemerer bought a Maroon Metallic, five-speed manual-equipped Honda Accord LX brand new in June 1978, when he was living in Pennsylvania. Now a resident of Beverly Hills, California, he has maintained and cherished that two-door hatchback for 43 years, and Rodney knows firsthand how difficult it is to keep the car running and looking factory-fresh, considering the near-total lack of replacement parts. When a virtually identical (save for its paint color, dealer-added accessories, and California-spec emissions controls), running-and-driving ’78 LX came up at an online auction last autumn, he took a chance and bought it, sight-unseen, with the idea that it could be a complete source of parts for his own car.
