Idemitsu Full Synthetic Rotary Racing 20W-50 Engine Oil - 1QT

The order was delivered on time and product was as described, in good condition.

While this oil may work fine for the specific application it is meant for, I am using for an different application. I like the high moly content, but cannot find any info on zinc content. For the application I am doing, I want high zinc like many other racing oils. I contacted the seller and they did not know the specs and said to contact the manufacturer. The manufacturer's website does not provide any details and have not yet responded. I am looking for the parts per million (ppm) of zinc as it is important to protecting metal surfaces. The oil has a very mild smell, not like another racing oil that I use that almost smells like diesel. The color of the oil does not appear to have extra dye in it which is good. The feel/thickness of the oil is similar to another 20W50 racing oil I have.

Its great to find a specialty oil for rotary engines! It works well and Idemitsu makes some of the best oils out there!

While this oil may not be specifically formulated for racing applications, it offers several positive qualities that make it a suitable choice for various purposes. Pros: 1- High Moly Content: The presence of molybdenum can help reduce friction and wear. However, this is what on the can/ bottle, I cannot verify. 2- Mild Odor: The oil has a subtle scent, making it less offensive than some other high-performance oils. 3- Smooth Texture: The oil has a smooth consistency, ensuring optimal lubrication. Cons: Expensive: Compared to other motor oil in the market, this one is a bit expensive. I know, I know, inflation and all, still, this is a bit much. 2- Limited Product Information: The manufacturer could provide more detailed information on the specific additives and their concentrations. Overall, this oil is a solid choice for various applications. If you're unsure about its suitability for a specific purpose, it's recommended to consult with a knowledgeable mechanic or engineer.

I am a bit of an oil snob and I gotta say that Idemitsu makes the best engine oils for racing application but also good for just daily driving. I feel like everybody knows they are #1 on the transmission fluid scene but overlook their oil... Do not overlook them, it is quality stuff.

what can i say its oil... check your engine and put this where needed.

Just like it says in the description, and since I don't have a materials lab to make sure that it's 20w50 or even motor oil for that matter, I'm not going to make any claims about that. It's 16 ounces of a dark fluid that I put in an engine and it did nothing wrong to it, so that gets it 4 Stars because only a name brand is going to get 5.
