Oil Levels.

[Guy Paris]

Hey Guys,
`I am looking at my Cessna Service Manual 1974 thru 1980 (for) Model 337 & Turbo Series. Paid 100 bucks for it in 1992, time has really flown! I am in the servicing sheet (sheet 2 of 4) change 7. (page) 2-15....

NOTE

Oil capacities for the aircraft are given in the following chart. to minimize loss of oil thru the breather, fill to specificied oil level on dipstick for normal operation (flight of less than three hours duration). For extended flight, fill to FULL mark on dipstick. Do not operate with less than MINIMUM-FOR-FLIGHT quanities listed. If an external oil filter is installed, one additional quart of oil is required when filter element is changed.

CAPACITY (TOTAL) 8, CAPACITY (TOTAL WITH FILTER) 9,

NORMAL OPERATIONS 7, MINIMUM FOR FLIGHT 6....

I copied this out of the book as close as posibile, remember the yrs, and models. The book also says the leveling marks are two screws on the pilots side below the side window. One could place a level across them to see if what you think is level is indeed level... How about when one next changes the oil and adds the required amount, (9), (8), or (7) one marks the that spot on the dip stick? The next time I change the oil and filter I am going to put in (8) quarts, run it wait 30 minuts, the book says (5) or (10) minuts and see what the stick reads, then I will mark that spot as (7), then I will eye ball it for the quart above for extended flight and a quart below for minimum.... Hey GMAs, would you know if this page has been superceded? Guy ....old72driver....
