Frequently Asked Questions

Do you check all fluids at every oil change visit?

Yes — every time. Engine oil, coolant, brake fluid, power steering, transmission, and washer fluid are all checked and topped off during any service visit at Mach1. It’s not an add-on.

My brake fluid keeps dropping. Should I just top it off?

No — brake fluid should not be consumed during normal operation. If the level is dropping, there’s a leak somewhere in the system. Topping off without investigating the source can give false confidence while the underlying problem continues.

Can the wrong coolant type damage my engine?

Yes. Modern vehicles use specific coolant formulations (OAT, HOAT, Dexcool, Motorcraft) that are not interchangeable. Mixing incompatible coolant types creates a chemical reaction that deposits scale, damages aluminum components, and compromises the cooling system.

What is DEF and does my truck need it checked?

DEF (Diesel Exhaust Fluid) is used by the SCR (Selective Catalytic Reduction) emissions system on 2011+ diesel trucks. When the DEF tank gets below 10%, most trucks warn and eventually derate engine power. We check and top it off on every diesel service visit.

Do you service all makes and models?

Yes — gas and diesel, trucks and daily drivers. Hillsboro, Beaverton, and Portland metro.
