Bill White uses Lucas Synthetic Oil Stabilizer in 1999 Mitsubishi Galant V6

I recently purchased my near mint condition Galant V6 with 77,000 miles on it. It's my "weekend" car, I run a Toyota Echo as my grocery getter and daily driver. First thing I did was pull it into my shop and start filling it with Lucas oils. I have been nothing but impressed with your products, they take the knocks, pings, and power loss right out of the vehicle. I especially noticed an increase in horse power when I used the oil stabilizer along with 3.5 quarts of Castrol Synthetic oil. Auto repair or maintenance prices here average about $100 per hour, a full on synthetic oil change with stabilizer can easily run $80.00 and up. I was able to do it myself for about $36.00 and I know it was done right. The V6 is getting 0 to 60 in about 8 seconds which is not bad considering it is all stock except for the exhaust and that is FASTER than what the new ones are rated at. This is a heck of a lot of car for $6,500 and your products make it that much better. Who needs to spend $30G on a car when Lucas is here? THANK YOU for making a product that is actually worth buying.
