Thank you

“… one concern I have always had with the car is that with limited use, low road running and iffy carburation is fuel dilution of the lube oil. Oil Spy has helped me to keep a check on this and allowed me to gauge when an oil change is required more accurately. Oil Spy is the only way of doing this other than laboratory analysis, for this I thank you”.
