Oil and mpg

Never been a fan of rotella, but any products Lucas produces, especially the oil stabilizer, are outstanding and well worth the cost. In my experience and IMHO.

 

This has been a Round Table dicussion for years.I never got a answer.But-this is some interesting reading for all of us.Lubricants(synthetics) at page 13.

Lol I just put lucas in a couple of weeks ago. I also noticed an improvement in the mileage. Need more time to really determine. Luckily I have the same run for a few more months

 

Every time I get my truck serviced the mileage goes up. Could it be the new fuel filters ? Could it be the fuel injector cleaner I prime the new filters with ? Could it be the brand new oil ?

 

Definitely maybe! LOL

 

I used to throw a bottle of lucas in my old 360 gasser. Never noticed any difference. A little increase in oil pressure and lifters were a little quieter. I got the same result running 15w-40 in it instead of 10w-30 lol.

 

I average 9.2 to 9.5 But my truck is governed at 60. Been trying to get to 9.9 for a 6 cent fuel bonus, maybe I should try the lucas.

 

Buy new fuel filters and a gallon of the fuel injector cleaner. Fill up the new filters with the injector cleaner then replace them on your truck and I guarantee your mileage will go way up. Enough to get you to 9.9 that I don't know but I guarantee your mileage will go up. What type of setup do you have ? Mileage into the 9's is very very very good.
