Our tech manager gets questions all of the time specifically about our motor oil. Here are some of the most popular questions he answers on a daily basis!
Is Royal Purple synthetic motor oil?
Yes. Royal Purple Motor Oils are composed of a proprietary formulation of synthetic base oils and synthetic additives containing iso-paraffinic diluents.
Are Royal Purple lubricants compatible with other motor oils?
Yes. Royal Purple lubricants are fully compatible with mineral or synthetic oils. No special procedures are necessary when switching to Royal Purple.
Can I use Royal Purple in my new car?
Yes. Royal Purple currently offers many viscosity grades of API-licensed motor oils. To allow for proper break-in of the engine, Royal Purple recommends waiting until the manufacturer’s first scheduled oil change or a minimum of 2,000 miles in new gasoline engines. Allow 8,000 to 10,000 miles before using Royal Purple in diesel engines.
How many miles can I go between oil changes?
Royal Purple suggests following manufacturer’s recommended oil change intervals for vehicles under warranty. Vehicles no longer under warranty can double or triple the number of miles between oil changes depending on the vehicle, its condition, the way it is used, and the oil filter that is used. For guidelines specific to your vehicle, contact our technical department at rrpautotech@royalpurple.com.
Can your motor oils be used in older engines?
Yes. Mileage and/or age are not factors when used in a mechanically sound engine. In high-mileage applications, we recommend running a minimum of two short (3,000 mile/5,000 km) intervals before extending the oil drain intervals. This will enable Royal Purple’s high solvency to remove existing deposits gradually. These deposits can restrict oil flow, if it is excessive, and reduce the oil service life significantly.
Will synthetic oil cause my engine to leak?
Properly formulated synthetic oils will not usually cause an engine oil leak. Synthetic oils have a higher degree of natural solvency that can clean and remove deposits left by previous oils. The removal of extensive oil deposits can expose marginal or damaged oil seals that could leak. If an engine has excessive oil consumption (i.e. greater than 1 quart/1,000 miles) we recommend solving the oil consumption problem before switching to a synthetic.
Does Royal Purple maintain its purple color after it’s put into service?
No. The dye used to color the oil dissipates shortly after being put into service. At some point the color will turn brown.
Where can I find Royal Purple products?
A number of retailers provide us with a listing of the products they regularly stock. You can find this information on our dealer locator page. Many retailers will special order products they do not regularly stock. A number of online ‘e-tailers’ such as paceperformance carry all of our consumer products.
Should I use an oil additive with Royal Purple?
No. We strongly recommend against using any oil additives as do most automotive manufacturers. Engine oils are formulated with a fine balance of additives (anti-foam, corrosion inhibitors, anti-wear, detergent/dispersants and oxidation inhibitors), and more does not mean better. The use of an oil additive could upset the balance resulting in reduced performance.
Is a special oil filter required when using Royal Purple?
While no special oil filter is required, we recommend upgrading to a high quality oil filter. Royal Purple now offers extended life oil filters. A high quality filter will prevent contaminants from circulating through the system and causing damage. Our oil filter information page will provide more details or visit our dealer locator to find the dealer nearest you that carries our new filters.
