Aviaid Oil pan capacity

[Lee Patterson]

I have the Aviaid 289 GT40 oil pan (with the starter notch on the right side) and their dipstick on my 302. The spec says the pan is a 6 quart pan. I've got 6 quarts in total in the motor and using a standard Wix SBF 51515 oil filter. Motor has been run multiple times. Oil level sitting at the "low" mark on the dipstick. Called Aviaid and asked if it's 6 quarts in the pan PLUS the filter (which is about 1 extra quart) or not - they do not know.

Anyone with feedback on this. Last thing I want to do is overfill it.

thanks

The best way at this point to “calibrate” the dipstick is to start the engine and once you see the oil pressure shut it off. Then drain the pan (with a clean pan) and measure out 6 quarts and put it in the engine, give it a few minutes to drain into the pan and then check the dipstick (twice after cleaning it) to see if those 6 quarts falls in the middle of the normal range. If it doesn’t, most custom dipsticks can be shortened or the length of the dipstick tube to make it right.

Thanks for the reply. Basically I’ve done that. I filled the filter which took nearly a quart and put the remainder plus 5 quarts in the motor. Motor has been run and stick shows low. If I drain that oil it will be less than 6 qts given the fact the filter is saturated.

I am basically confused as to why Aviaid would call it a 6 qt pan but not consider the filter.

Thks.

Lee, I’ve always been under the belief that when a manufacturer says it’s a (fill in the blank) quart oil pan that it is the capacity of the pan itself and doesn’t include any of the other components of the oil system, like oil coolers, filter, hoses, internal journals, etc. It seems like it’s a topic of debate with other aftermarket manufacturers such as Moroso pans.

Devin - as was I.

I did find this buried on the Aviaid website: "We rate our oil pans for static level in the pan. This is the quantity of oil that will fill the sump up to about the underside of the hard tray bolted into the pan. We recommend that the 1st time you fill the pan in the car, with the car flat on the ground and the pan empty, you add 1 quart less than the advertised number of quarts and mark the stick. Add 1 more quart and mark the stick again. This is a high-low marking procedure. Then start the engine. Let everything pressurize and fill, shut the engine down, and let everything drain down for a few minutes. Then add oil to bring the level back to the top mark on the stick, noting how much oil is required to fill the pan back up to the top mark. The total of the added oil plus the initial fill will give you system capacity. This now includes lines, filter, cooler, whatever. From that point you can adjust level to suite your requirements. Some will run a little more, some a little less, depending on usage."

I think this confirms the pan is designed to hold the 6 quarts.
