## Questions & Answers

**Q: Is this oil used in the motor?**
A: No

**Q: Will this pump oil work for the Simpson 4240 pressure washer?**
A: It should work in any pump

**Q: Full synthetic 15 W 40 non detergent for  pressure washer pumps  ?**
A: The pumps take non-detergent oil so if it says it is for pumps then it is non-detergent.

**Q: Is this nondetergent oil?**
A: I don’t know for sure but I assume it’s specially for the motors designated. I also assume that detergent is not necessary and that it is non-detergent since it is not shown on the container.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Pump oil
*by C***N on October 16, 2025*

OE pump oil, correct stuff when you rebuild pump.

### ⭐⭐⭐⭐⭐ As delivered and supported oil by manufacturer

As described and am glad it's an option to buy officially supported oil.

### ⭐⭐⭐⭐ Manufacturer required oil
*by G***N on August 19, 2022*

This is the factory required replacement oil for Karcher's pressure washers. For mine, the refill volume needed is 100 ml so this 1 liter container container will provide 10 refills. The oil is expensive for a non-detergent, synthetic, 15W40 oil of 1 liter in volume. I know of one US made equivalent that is $10 less costly for a similar container size. If frequent flush and refill was required by Karcher, this container size would still be excessive given the expected life of the pressure washer itself. So, IMO, good oil, but too much and too costly.
