I was concerned at first, when you said you were out of stock, and the oil was on back order. I was about out, which means no flying, but you came through more quickly than I envisioned. I still wish you offered this in quart size containers.

I would like to buy it in the quart size , but is not available . Much prefer a bigger container, instead of so many small ones.

The oil itself is fine, but since Quaker State has taken over for the same Pennzoil product, they have done away with the latching ring under the cap (ironically still in the picture). This allows the caps to come unscrewed during shipping, resulting in an oil-soaked box at your front door!

Q: Is this the same oil as the Pennzoil was? Any compatibility issues from mixing the two?

Pennzoil has been replaced with Quaker State 2-stroke oil. There are no known issues in the mixing the two.

Q: I need to buy two stroke oil but obviously I am concerned about switching to an unknown oil for my airplane. Is this oil truly a replacement? Does the Quaker State 2 cycle oil meet API-TC specs?

Yes, it is a true replacement. Per the Quaker State website: Meets current JASO standards FA & FB and exceeds API service level TC.

Q: I have Rotax 503 in my airplane. I have used Pennzoil since the beginning and now can't find it anywhere... Is this oil going to be ok to replace? It says it only mixes 40-1, I need 50-1, and can I mix at that ratio?

This is the replacement for the Pennzoil. You can mix at 50-1 without any trouble.

Q: I have a Rotax 447 been using Pennzoil 50.1 - 8 oz of oil to 3 gal of gas, The QS is 7.8 Oz of oil to 3 Gal of gas, Will it be ok just to add the 8 OZ of QS to 3 gal of gas and be ok for 50.1?

Yes, this will work just fine.

Q: Is this Quaker State 2 cycle air cooled oil a mineral or synthetic oil? Can it replace CPS AV-2 Oil for Rotax engines?

Per Quaker State, this is Conventional composition oil. Not synthetic. Yes, this a 2 cycle oil, same as AV-2 for use with Rotax engines.

Q: Is this Quaker State 2 cycle oil suitable for free air cooled (has no fan) 2 cycle engines?


Q: How much gasoline to use for 3.2 o/z of quaker state oil?

Yes, this is a 2-cycle oil which per the notes on the web description has a 40:1 ratio, so 3.2 oz of oil should treat about 8 gallons of gas, but the end user must review the instructions on the container before mixing to verify the ratio.
