A little over a year ago I left work in my 1996 Dodge Neon when it started to overheat. Gauge rose steadly, casing on water pump broke open and spilled entire contents of the cooling system all over the highway. I drove 6 to 8 miles all the way home with no coolant with the car losing power. Barely got it into the driveway shooting steam like Old Faithful. Well, I let it sit for over a year. Got it back today, along with a $378.00 bill to replace the water pump and timing belt. To my surprise I did not need a ring job done on it. Car drives great, does not smoke. I can only attribute this to Havoline motor oil. i had 10w-30 in it when it happened, have since changed it back to 5w-30 to clean up any junk that may have made its way back into motor, plus the 5w-30 was extra I had on hand at the time. In my own personal opinion, this is the best performing conventional motor oil I have ever used. I will be a loyal user of it in the future from now on.
