Fluids, Filters & Shop

Fluids, Filters & Shop covers the maintenance items that keep a diesel healthy between repairs: the oil, filters, coolant, lubricants and shop supplies you go through on every service. Diesels are hard on oil and sensitive to contamination, so using the right fluids and changing them on schedule is one of the cheapest ways to protect an expensive engine.

Shop diesel engine oil from Motul, Red Line, Royal Purple and LIQUI MOLY in the common diesel viscosities, along with oil filters, coolant and additives, grease and lubricants and sealants. We also carry service kits that bundle filters and parts for a complete service, plus heat control products like heat shields, sleeves and exhaust wrap from DEI.

Pick a category below to get started. If you are not sure which oil or coolant your engine calls for, check your owner's manual or the engine manufacturer's spec first; it matters more than the brand on the bottle.
