On the run to St. Louis MO today in the 153K mile 2000 Towncar we hit MPG with the Ceratec that ranged from 23.5 to 26.5. While not much in the way of hard facts I do think Ceratec may improve MPG as much as MoS2. We will plan to do more gathering of data on our trip to MD next month. The best way to get 2 more MPG so far has been to cut forward motion by 15 MPH.
It is amazing how much less gas it takes to go 55 than 70. One wild card is at 3500 miles of running the Ceratec (normal) we had to add a quart and we used Mobil 1 High Mileage 10W-40 which contains Moly from Mobil and I think is perhaps the best of all motor oils on can run in an older engine. It is slick and we have started using it as cutting oil when sawing steel with the Sawsall and drilling steel. It makes blades last much longer and keeps them from turning blue from heat. Tue evening we sawed the remains of an 8' 1300 Tommy Lift Gate off the rear off the tail of our 16' dump bed and only used 4 blades.
On our test Ceratex engine that we ran for 1,000,000 RPM's the metrics were simple. My butt got tired of being out in the cold listening the the 325 Polaris 4-stoke do a fast idle for 11 hours over two days.
As you read we bought it from a guy that blew an oil cooler line running down the highway (40 MPH is max on that machine stock) until it was knocking loud enough for him to hear it. The rod bearing inserts were worn paper thin and the crank shaft was really chewed up and the connecting rod was scrap metal and totally black on the lower end. The rest of the engine parts still mic'ed in tolerance and were reused for the 11 hours of fast idle testing. I covered the results when I posted it last Jan. We did pick up a tight used bottom end but due to distractions of life when it got warmer we did not rebuild the engine so now we hoping to get on it when it gets too wet to work outside. With the old back hoe we have cleared an acre of small trees for another parking lot at church and I still have to put that on grade and haul the gravel from a pit two miles up the road.
Back to Ceratec we plan to run it in both of the 325cc Polaris ATV's just to increase the odds of not trashing an engine use to total lost of motor oil. We will be using the Mobil 1 High Mileage 10W-40 in all of our air cooled engines going forward and other gas engines that we change ourselves. If Ceratec is not in the crankcase then I expect MoS2 will be or Archoil AR9100.
