FAQS

How do I become a Red Line Oil Dealer?

Visit our dealer section of the website for a complete list of distributors and contact one in your area. You can also call us at 800-624-7958 for a dealer info packet or a regional reference to a distributor. Qualifications depend on your type of shop, how long have you been in business, resale numbers, etc.

How do I know which product variation to use in my car?

Reference your owner™s manual and make a direct cross-reference from there. Most engines a use 5W30 or 10W30 motor oil for general use, 10w40 if you live in a hotter climate. Our most popular automatic transmission fluid is D4 ATF where a Dexron III, Mercon, or Mercon V is called for, as well. Our C+ATF works in place of Chrysler ATF+3. Our latest D6 ATF is specified to replace Dexron IX and Mercon SP (found in 2006-up GM vehicles and 2004-up Fords, respectively). In reference to gear oils, your manual transmission will likely call for an GL-4 type gear oil (like our MTL or MT-90), an ATF, or possibly a GL-5 product like our 75W90 NS.

How often should I change my Red Line oil?

It depends on how you drive. If you do a lot of city driving or low speed/low frequency driving, we recommend oil changes at 7500 miles. Vehicles that see more highway driving can go a maximum of 15,000 to 18,000 miles with an oil filter change in between. Modern filter technology and the latest, clean-burning fuels have reduced the solids that contaminate oil, so frequent filter changes aren't usually necessary.

Can I break-in my engine on Red Line Oil?

We recommend using petroleum 10w30 motor oil on break in to ensure proper piston ring seating. If you allow 1500 to 2000 miles in a street engine or 20 to 30 minutes on the dyno at low rpm, the rings will have had sufficient time to seat and the high initial break-in wear will have occurred.

Do you recommend special oil for driveline break-in?

A differential or transaxle will break-in with a synthetic product without issue. Some aftermarket ring and pinion suppliers recommend adding additional friction modifier to reduce temperatures and friction during the critical break-in period. Drain this mix after break-in and re-fill.

How can I get Red Line Oil to sponsor my race team?

We carefully review all racing proposals submitted, but please understand that we receive nearly 1,000 proposals each year and cannot return your proposal.

Is WaterWetter compatible with antifreeze?

WaterWetter is compatible with all antifreezes including the new extended-life types that are śfactory-fillť in your new road car. Simply pour it in.

Is a special oil filter required to use Red Line Oils?

No, we simply recommend using a quality filter, whether it™s for your engine or transmission.

Should I flush my engine or driveline before using Red Line™s synthetic lubricants?

A flush isn't necessary or advised, as Red Line™s products are compatible and will mix with other synthetics and petroleum products.

Will using Red Line products void my vehicle™s factory warranty?
