No. AMSOIL is a solo act. Everything your engine needs for lubrication and protection is in the oil. Additives can upset the oil's precise chemistry, or worse, interact with the oil in unpredictable and harmful ways. Save your money ... and your engine. Skip the additives.

See Oil Additives for more detailed information. In regard to AMSOIL Super Duty Oil Filters being inferior to Wix (NAPA) filters based upon visual inspection, AMSOIL Filters have an inner beauty that's not visible to the human eye.

There is a continual debate about what type of oil to put in your car. My own opinion is that, if you use a high-quality motor oil of the correct weight, it doesn’t matter which one you use. Some people advise against putting synthetic oils in VWs or Porsches. There is a myth that they do not dissipate heat as well as conventional "dinosaur" oils. This is untrue—some of them have tested out better than dino oils.

Why does AMSOIL say to change the AMSOIL SDF Oil Filter at six months regardless of the mileage. I have only gone 5,000 miles and figure that I could go the whole year without changing it and be good.

Modern engine oils and fuels are carefully formulated to offer the best possible performance over a wide range of operating condition. There are occasions where an additive not contained in the oil or fuel will improve performance in one respect or another. However, there are also additives that will cause harm to the system. If aftermarket additives are used they should be thoroughly tested and offer more proof of performance than simple testimonial letters or anecdotal evidence.

Justice Brothers products can be used from the very first day of a new car or at any time on older vehicles. Justice Brother's oil additives will reduce engine wear and friction, but will not interfere with the "break-in" period of a new car. Yes, Justice Brothers Power Steering Conditioner & Treatment will correct squealing and hard spots and stop most seal leaks. The product is also good to use in new units to prevent wear.

You do not need to use a 5W-20 oil. Do not let your dealer/owner's manual scare you by telling you that you have to use it for your warranty. Once you know the facts and the Federal Magnuson Moss Act law, you will be much better informed to protect your rights and use the type of oil you want to use. See the 5w-20 Issue for more detailed information.

Yes. When used in mechanically sound engines, AMSOIL Motor Oils can reduce oil consumption. However, AMSOIL Motor Oils will not "fix" an engine that has other mechanical problems causing excessive oil consumption.

It can be used in conjunction with other Rapid Set® Concrete Pharmacy® items or certain approved additives.

Anti-Oxidant - Reduces bulk oil oxidation which helps to prevent engine deposits, sludge, and high temperature thickening Detergents/Dispersants - Help maintain engine cleanliness by suspending sludge and wear particles in the oil, so that they can be rained out during oil change.

Most quality Motor Oils contain all the necessary additives, specifically balanced to afford complete and superior engine protection. The use of over the counter oil additives is not necessary to obtain the protection required by vehicle manufacturers. In fact, supplemental oil additives and engine treatments are not recommended by many car manufacturers - and are specifically recommended against by some (GM, Ford, Honda, etc.)

None. We don’t use other additives like BHA, BHT ,TBHQ, etc. The oil is a pure product expeller pressed from the kukui nut. Oils of Aloha Kukui Nut Oil is expeller pressed. We use no solvents of any kind in the production of the oil. Kukui nuts are fed into a screw press and the oil is literally squeezed out. This process generates a minimum of heat and that helps to protect the oil. After expelling the oil goes through a filter press to remove particulate matter.

Yes, it is safe to use AMSOIL 10W-30 in an engine that calls for an SAE 30 petroleum oil. All 30 weight oils, whether a 5W-30, 10W-30 or straight 30 weight, perform as 30 weight oils at operating temperatures. The "w" indicator in multigrade oils (10W-30) refers to the oil's cold weather properties. You can think of "w" as standing for "winter" Therefore, a 10W-30 oil meets the "10w" criteria when cold and the "30" criteria when hot.

Additives are used in lubricating oil to change or alter or enhance its properties. Base oil as such cannot be used in most of the present-day lubricating applications. Their properties - like resistance to heat, oxygen, wear etc - have to be increased. This increment is done with the use of these additives. To increase the resistance to oxidation, we add 'antioxidants', to increase resistance to wear, we add 'antiwear additives'
