Lucas Oil 10016 Complete Engine Treatment,16 fl. oz

Used the first bottle when I bought my 2007 Jeep GC in the fuel tank. Hard to say it improves the MOG but it was added more as a cleaner and preventative maintenance additive. I also use the Lucas fuel treatment on every fill-up. Run the Jeep on a full tank until about nearly empty, averaging about 400 miles. Will use the second bottle in with the engine oil this time. See how we get on. I have used Lucas oil products in the past and never had any problems, so more than happy to keep using. As mentioned, preventative maintenance use which I’m pretty sure it ticks the box.
