Strange engine oil level readings

The oil filter is taking up the difference.

That occurred to me. but I don't think the filter can hold 2.5 qts of oil, can it? Also, I checked the TSIO360 engine manual, and it shows the oil filter adapter and oil filter as original design equipment. By 1978, I believe Continental was putting oil filters on most engines from the factory.

Maybe check and see if both dipsticks are the same. Cant imagine you have 2 that are incorrect.
I would go with whats on the dipstick.
I now keep my naturally aspirated engines at 6 qrts instead of 8.
Much happier w 6 now.

Thanks for the tip Philly - I agree no need to always run full of oil. Maybe on a long cross-country, but that's about the only time I can think of I'd want full oil.

Same here. I realized after the first two oil changes (and after removing lots of oil from the AC belly) that the dipsticks weren’t calibrated. We put in 8 quarts and it reads 6 quarts. Before that I thought my engines were “burning” oil but it seems it’s just been blown out the breather tube. I use the 6 quart mark now (knowing that I filled it with 8) until I can get the dipstick calibrated.

THIS^^^
I put in the remaining 1.5 qts, for a total of 8 qts added, plus a filter change. Filter was not pre-loaded with oil. Started the motor and ran it briefly, came back the next morning, and the dipstick reads 5.5 qts. So that's my new 8 quart baseline reading.

The dipsticks front vs. rear have the same initial P/N, but different letters at the end. I will continue to monitor and investigate.

If anyone has access to a TSIO-360 parts catalog, please post the proper dipstick P/N for the TSIO-360CB engines. Thanks.

Check out Continental SIL 00-7C you will have P/N 632062-20A1 or 632062-19A1 depending
on the last digits of your engine model ie TSIO360CB3. you might also check to see if the dip stick tube is coming out of the case.

Thanks Kim. The rear engine is a TSIO-360CB-6B. The dipstick currently installed is a 632062-19 BK. Photo attached.
