**Q: Can you use this on a Homelite 2700 psi pressure washer?**
A: not positive but im sure because its a non detergent oil

I'll let you know that I used this for a Comet pump...... I know, I know, but let me tell you it's lasted and lasted and lasted (even longer than the energizer bunny). It's expensive for what it is, and since you can use a non detergent 30WT oil, maybe even more so, but it's good oil, I've had no pump issues in the last 10 years of owning my pressure washer pump (which as an axial cam) and now a piston pump. Oils are getting better every year, and most are very similar, but since this is what shipped with my pump originally, it's what I'll continue to use. I have not needed customer service so can't comment on that, but would not hesitate to buy this brand, from this seller again.
