We wanted to let you know that when you told us about the 20% increase in mileage using K100-G+, we put it to the test. Our vehicle owner’s manual states that our 1999 Buick Park Avenue Ultra has a 3.8 supercharged motor which requires at least 91 octane because of a heavy spark knock with lower grades of gasoline. You told us to try 89 octane because K100-G+ has a booster in it, so we did! Here are the results after just one tank full of 89 octane gas:
- No spark knock
- MPG before test on 93 octane = 20.4
- MPG after test on 89 octane = 24.3
- Car runs great with no problems
Now we can buy cheaper gas with better results and save 2 times the cost of the product! Keep up the good work! Thanks a lot!
From Cheryl in Wisconsin:
My husband tried it in our 2004 duramax diesel pickup and he can’t believe how great the results are! We were having injector problems. Lots of black smoke. Went to the dealer, not covered under warrantee. We couldn’t afford to fix it at $4,000.00… Then after adding K100 it quit smoking and is running just fine. We pulled our camper to Rochester MN. No problems. Today, I saw him out there trying to make it smoke, couldn’t do it!
From Ken in California:
Every morning my Silverado has started with a high low idle and check engine light. Our temperature drops from 58 to the low 20′s. I was pretty sure I had water in the fuel from condensation. Last night I used K100 and this morning GREAT idle and no check engine light or codes. This time of year air condenses in gas cans/gas tanks ending up with water in the tank. K100 works.
