Club Homepage Forums Classified Ads Buy & Sell - Everything But Airplanes Looking for a Cessna 150 fuel dipstick

The reason I originally posted my request” LOOKING FOR A CESSNA 150 FUEL DIPSTICK” was: I was at the fuel pump at KIJD late January early February 2025. The person in front of me (originally from Vermont) was fueling his C-150. Had I been smart enough to get his contact information I most likely never would have made this post.

I told him that I owned three commercially available fuel dipsticks and none of them were accurate. He showed me a fuel dipstick he got from the Cesnna 150 / 152 club some years ago. It was the nicest fuel dipstick I have ever seen. It had graduates on it for both the 150 and the 152 for both usable and unusable fuel. The next day I wrote a post trying to find out how I could buy one of these fuel dipstick. I received a reply that l was four years too late. That the guy who used to make these for the club no longer was making them.

What I am looking for is someone who has one of these C 150 fuel dipstick that the Cessna 150 / 152 Club used to sell. My first choice would be to buy one from someone willing to sell one. However, I would be just as happy to meet up with someone near by who has one so I could mark the graduates on a wooden dowel.

Again, thank you everyone who took the time to reply to my post.

Mike, your comment was spot on! “Sporty’s GET TO WORK” especially since Cesnna built, 23,839 C-150’s and only 7584 C-152’s. Seems backwards that you can only buy a Cessna 152 fuel dipstick and are told by others to subtract 1 gallon from what it reads to get unusable fuel for a Cesnna 150. by the way, well that is better than nothing it is definitely not accurate.

Yes, Sporty’s Currently sells a C-150 / C-152 fuel dipstick. Please don’t waste your money like I did and buy one. Normally, Sporty’s has been a great source for aircraft supplies. However, this time they were a real disappointment. The fuel dipstick they sell is a cheap, narrow, clear plastic straw with a strip of plastic with graduates printed on it stuffed inside the clear plastic straw. The end is folded over to try to hold the strip of plastic with the scale on it in place. It is also graduated for total fuel, not usable fuel which can get someone in trouble if they’re not careful.

Ron, Hung & Jay thank you for answering Steve’s questions. Your advice was spot on.

What I find hard to believe is: With so many Cesnna 150s out there how difficult it is to find something as basic as an accurate, usable fuel dipstick for a C-150 and how hard people have to work to develop one.

Typo / correction to my last post:

It should have said “subtract one gallon from what you read on the C-152 fuel dipstick to determine the USABLE fuel in a C-150 (not unusable).

The logic being applied to this kind of thinking is the POH for the C-152 states 1.5 gal. unusable (0.75 gal. each tank). The POH for the C-150 states 3.5 gal. unusable (1.75 gal. each tank.). The difference in unusable fuel between the C-150 and C-152 (per standard fuel tank) is the C-150 has one gallon more unusable fuel than a C-152 per fuel tank.

If you look at the C-152 usable fuel stick you will note the zero on the fuel stick don’t start at the bottom of the stick. It starts about 0.75 gal. above the bottom of the fuel stick.

Logic would lead you to believe that zero on the C-152 fuel stick when using it to measure usable fuel in a C-150 is really at the one gallon mark.

The problem with this logic is the graduates on the fuel dipstick are not correct and if you are adjusting your fuel load to try and stay within the 1600 lb. max weight (which many C-150 owners need to do) then you will be over weight.

I had a 152 FuelHawk dip stick [mypilotstore.com] when I had my '80 152. I used it to cross-check with what the plane's fuel gauges were showing to make sure the gauges weren't GROSSLY off. But I wouldn't bet my life on what the FuelHawk showed when there were about 2-3 gallons usable in each tank.
