How do I use FHS Smokeless Motor Oil?
How much FHS Smokeless Motor Oil do I need?
Most 4-to-6-cylinder engines require 5 to 8 qts for an oil change. However, we recommend you consult your vehicle owner’s manual for the most accurate oil quantity for your particular make and model.
How long should I go between oil changes?
FHS Smokeless Motor Oil lasts up to 10,000 miles between oil changes though actual mileage varies depending on vehicle type and usage. We recommend checking your oil regularly as you would with conventional motor oil.
Will it affect the oil pump or seals?
FHS Smokeless Motor Oil should not affect these automotive systems. However, we recommend oil pumps or seals be examined by an automotive professional during regular maintenance inspections.
Can it be used with other oils or additives?
FHS Smokeless Motor Oil is designed to work alone and should not be used with other oil products or additives. It is a complete oil package with all the protective and lubricating properties necessary for your engine. If you use FHS Smokeless Motor Oil with other oils, you will get smoke. Also mixing different brands of oils can reduce the protective qualities of the oils.

Will it fix emissions problems?
FHS Smokeless Motor Oil will generally reduce emissions resulting from oil burning. Not only does it stop visible smoking, actual tests on vehicles which failed emissions exams show that it can improve emissions enough to pass emissions tests. It can drastically reduce hydrocarbon (HC) and carbon monoxide (CO) levels to acceptable/passable emission limits.
Disclaimer & Guarantee:
For oil related smoking problems, FHS Smokeless Motor Oil works over 99% of the time. However, proper diagnosis of the source of engine smoke is important, as this oil will have no effect on coolant, fuel, or carburetor related emission or smoking problems.
FHS Smokeless Motor Oil should not be used in conjunction with any additive or other motor oils. Mixing other oils with FHS Smokeless Motor Oil will cause vehicles to smoke (the non-smokeless oil still burn and create smoke). If sludge buildup is present, a system flush may be required before adding FHS Smokeless Motor Oil.
Note to automotive repair professionals and auto dealers:
We recommend that you mention to your customers if a car is using FHS Smokeless Motor Oil, and please give our information so that customers know where to obtain more FHS Smokeless Motor Oil if desired. Honesty is the best policy.
