Yes, Rislone works with all petroleum-based motor oils including conventional, high mileage and synthetic. Rislone is also safe for use with PTFE-based engine treatments and will not alter the PTFE coating.

No, Rislone Engine Treatment is formulated to be left safely in the crankcase for the life of the oil change for maximum performance. It is not an engine flush and does not require draining. See similar questions...

Rislone Engine Treatment gradually dissolves and removes harmful deposits of varnish, sludge and gum from the internal metal parts without plugging oil passages. These deposits form within engines and can alter tolerances, stick valves and rings, cause noisy valves and lifters, and plug oil screens and passages. Regular use of Rislone Engine Treatment, with oil and filter changes at the proper intervals, will keep such deposits to a minimum. See similar questions...

One bottle of 100QR Rislone Engine Treatment 1 quart (32 oz.) is designed to treat 4 to 6 quarts of oil, this allows you to replace a quart of motor oil at oil change time. You can also use it to "top off" your system between oil changes. See similar questions...

Yes, Rislone Engine Treatment has the lubricating and protective capabilities of current motor oils, plus additional penetrating properties which do a superior job of maintaining long-term cleanliness and deposit control. Use of Rislone Engine Treatment will not void your new car warranty. See similar questions...

Yes, there is no harm in using a Synthetic blend or a full synthetic oil. There are many benifits to using a synthetic engine oil, such as ease of starting, lower operating temperature, and reduced component wear. For more information, visit the Mobil 1 site See similar questions...

No, synthetic oils have shown no advantages when used and in some cases have actually harmed engines used in boating applications. See similar questions...

Yes, Bar's Leaks is one of the only engine oil stop leaks that is compatible with all petroleum based oils, including synthetics. See similar questions...

It makes no difference because the revitalizant is compatible with any kinds of oil and fuel grades. It is chemically inert and will not react to these substances, and does not affect their viscosity. Oil is all but a "carrier" for the revitalizant delivering it to the areas where the friction occurs. XADO does not treat oil! See similar questions...

All motor oils are made up of base oils and additives. In general, fully synthetic motor oils contain non-conventional, high-performance fluids. Semi-synthetic oils (also called "blends") usually use a small percentage of non-conventional, high-performance fluids in combination with conventional base oil. See similar questions...

Cummins recommends that you not use synthetic motor oil during the break-in period of 5000-20,000 miles, based on the type of driving, to allow proper seating of the piston rings. Beyond that mileage it is OK to use synthetic oil. No. DaimlerChrysler and Cummins do not recommend the use of increased flow air filters such as K&N, because they can allow contaminants into the intake that can ruin an engine (scoring the sides of the pistons, etc.) See similar questions...

Any engine oil can be used as long as it meets the specifications listed in the engine manufacturer's manual. In addition to flushing your engine after your boat has been exposed to salt water: clean, wash, and dry all exposed metal parts and coat them with a preservative such as WD40. This will prolong the life of the exposed metal parts. See similar questions...

Yes. The terms “synthetic”, “semi-synthetic” etc relate to the type of base fluid from which an oil is blended. Apart from base fluids, lubricants also contain additives, all of which are synthetic. There are many types of base fluid which may be described as being “synthetic”, each having their own properties and advantages/disadvantages in particular applications. See similar questions...
