Dura Lube Severe Fuel System Cleaner, 16 fl oz

this duralube cleaner was put in a older car that i had bought to resale. i can tell the car started running smoother after just a short while driving it. Great price as just as good as some more expensive cleaners

This stuff is great but it did take me two bottles for my catalytic to clear, two separate tank fulls.

I used this with another, very similar top tier product to clean out the fuel/engine after is sat for longer than it should. I am certain both did exactly what they were supposed to do. Follow the instructions, they're straightforward and you'll see results, assuming of course that the issue(s) are not outside of what this cleaners purpose. I'd use it again to blast out an engine system that needed it, just add it one tank full away from an oil change.

Needed for my fuel injectors. Always works great.

I have not used it in a generator. I have used it to increase my acceleration and performance. Ease of use pour in to the tank.

This is superior fuel system cleaner. It's a little more pricey but worth it's performance. We are a repeat buyer.

great product it really helped

it does great and cleans the injectors as stated

I don't know how to review this product as I can't tell a difference. It may just be a bottle of alcohol, so, yeah

I have been using this for 30 years. I use all the treatments.
