I recieved some Uniglide lube which gives all the standard promises of the friction reducing lubes about FE and wear. They even threw in some of their gas pills to increase FE with it so I went ahead and tested both products. I have no way to A-B-A test with these product so I just did A-B. The Daewoo has 76k on it and I have no records of past history. I'm running 30w Rotella T in the engine and E15 for the gas.
Temperature 15 C, wind south 8-12, bi-directional runs N&S. After adding the Uniglide I drove around for 10 minutes before begining runs.
Without lube Avg 43.825
With Lube Avg 44.55
Increase FE 1.65% with the Lube
I had 10 gallons of fuel on board. I had disolved the pills in 10 oz of gas with took 4 hours to completely disappear. The gas turned from light to a darker brown. I completed the runs without, added the mixture and drove around for 20 minutes before begining the next runs. I'll run this mixture for the next 2 tanks and then do 2 tanks without and do again and see if the results change.
Gas Pills Weather was 10C winds 360@12, bi-directional runs N&S
Without Pills Avg 45.75
Increase of less the 1% I did 6 runs just to see if maybe the ECU had not adjusted to the mixture yet.
I talked to the quick lube guy and he said that he would do emission testing for free on this if I wanted to see if it affects it. Sometimes it pays to have duct tape all over your car. He was very interested in what I'm doing. I don't think I will because once the pills run out I don't think I'll be using them.
