Signature service

Read your engine's health in its oil.

Every oil change here can include a lab engine oil analysis that reads the wear metals, contaminants, and viscosity breakdown hiding in your used oil — catching bearing wear, coolant intrusion, and fuel dilution long before a warning light ever flickers. It's predictive maintenance for the engines that can't afford to surprise you.

Fluid services

The fluids that keep
your vehicle alive.

Oil, transmission fluid, and differential oil are the three services most often skipped — and the three that save you the most in avoided repairs. Here's what we do.

01
Diagnostics

Engine Oil Analysis

Lab-style analysis that reads the wear metals, contaminants, and viscosity breakdown hiding in your used oil. We send a sample out and translate the report into plain English — catching bearing wear, coolant intrusion, fuel dilution, and dirt ingestion long before a warning light ever flickers. Offered on every oil change and as a standalone sample for fleet and high-mileage vehicles that need a closer look between services.

With every oil change, or as a standalone lab sample for fleet & high-mileage vehicles
Signs you need it
  • High-mileage or hard-worked engine
  • Fleet vehicle due for predictive maintenance
  • Buying a used vehicle — want a clean bill of health
  • Recurring top-offs between changes

02
Engine oil

Premium Oil Change

Full-synthetic, conventional, and diesel oil changes done with the exact viscosity and spec your engine calls for — never a one-size-fits-all bulk fill. Every service includes a new factory-spec filter, a multi-point inspection of belts, hoses, and fluid levels, and the option to add an engine oil analysis on the used oil we drain so you leave knowing what's happening inside your engine, not just that the oil is fresh.

Every 5,000 miles (synthetic) or 3,000–5,000 miles (conventional); sooner for severe service
Signs you need it
  • Dark, gritty, or burnt-smelling oil on the dipstick
  • Oil change / maintenance light illuminated
  • Engine ticking, knocking, or low-oil pressure warnings
  • You can't recall the last change — time to reset the clock
See oil service pricing
03
Transmission

Transmission Fluid Change

Drain-and-fill or full flush service for automatic and manual transmissions, always using the correct ATF your unit specifies — the wrong fluid destroys a transmission faster than old fluid. We inspect the fluid's color, smell, and debris first and recommend the service your transmission actually needs. We won't push a flush a healthy unit doesn't need, and we won't refill a failing one without telling you what we found.

Every 30,000–60,000 miles (severe service: 30,000); check condition yearly after 60k
Signs you need it
  • Rough, delayed, or hard shifting
  • Burnt smell or dark, gritty fluid on the stick
  • Slipping or flaring between gears
  • Service interval overdue and fluid is original

04
Rear axle

Rear Differential Fluid Change

Gear oil service for the rear differential on trucks, SUVs, and rear-wheel-drive cars. Old, contaminated, or water-intruded gear oil turns abrasive and eats the ring and pinion — the whine you hear is metal leaving the gears. We drain the old oil, inspect the magnet for tell-tale wear metal, refill to the correct level with the gear oil weight your axle specifies, and recommend an interval based on how you actually use the truck.

Every 30,000–50,000 miles; sooner for towing, plowing, or off-road use
Signs you need it
  • Whining or humming from the rear under load
  • Clunk when taking off from a stop
  • Past the service interval or fluid looks milky
  • Towing or hauling regularly — heat breaks the oil down
Book rear diff service
05
Front axle

Front Differential Fluid Change

Front differential gear oil service for 4WD and AWD trucks and SUVs. The front diff is the most overlooked fluid on the vehicle — it works just as hard as the rear but gets changed half as often. We drain the old oil, check the magnet for metal that signals bearing or carrier wear, and refill to spec with the correct weight. Skipping it turns a $150 service into a $1,500 axle rebuild; we'd rather you never need the unnecessary repairs..

Every 30,000–50,000 miles; match it to your rear diff service for simplicity
Signs you need it
  • Noise or vibration when 4WD is engaged
  • Clunk or shudder on tight turns (AWD)
  • Service interval overdue — often never been done
  • Front axle submerged in water — change it immediately
Book front diff service
Diesel too

Diesel pickups & commercial trucks.

Diesel-rated oil, heavy-duty filters, fuel filter checks, and DPF/EGR inspections. We service 3/4- and 1-ton pickups through class 6–8 trucks on the same bays.

Questions, answered

Fluid service FAQ.

What is engine oil analysis and why does it matter?

Engine oil analysis is a lab test on your used oil that measures wear metals (iron, copper, lead, aluminum), contaminants (silicon, sodium, fuel, coolant), and viscosity breakdown. It tells you what's happening inside the engine while it's still running — bearing wear, coolant intrusion, fuel dilution, dirt ingestion — before it becomes a breakdown. We offer it on every oil change and as a standalone sample for fleet vehicles and high-mileage engines that deserve a closer look between services.

Can I get an oil analysis without a full oil change?

Yes. We can pull a sample at any time — during another service, at a fluid top-off, or as a standalone visit — and send it to the lab. It's popular with fleet managers running predictive maintenance programs and with anyone buying a used vehicle who wants a clean bill of health before committing. Call (216) 236-3728 to arrange a sample.

How often should I change my transmission fluid?

Most manufacturers recommend a transmission fluid change every 30,000 to 60,000 miles for normal driving. Severe service — towing, heavy loads, stop-and-go city driving, or hot climates — shortens that to about every 30,000 miles. We check the fluid's color, smell, and debris first and follow your vehicle's service schedule, never over-selling a flush that isn't needed or refilling a failing unit without telling you what we found.

How often should I change differential fluid?

Differential fluid is typically changed every 30,000 to 50,000 miles, or every 60,000 miles under gentle highway driving. Trucks that tow, plow, or see off-road use need it sooner because heat and contamination break the gear oil down faster. We service both front and rear differentials, inspect the drain magnet for wear metal, and refill with the exact gear oil weight your axle specifies.

How much does a transmission fluid change cost?

Transmission fluid service varies by vehicle and whether a drain-and-fill or full flush is appropriate for your unit's condition. We provide a written quote before any work begins so there are no surprises. Call (216) 236-3728 for a quote on your specific vehicle and transmission.

Do you service diesel trucks too?

Yes. We service diesel pickups and commercial trucks with diesel-rated oil, heavy-duty filters, fuel filter checks, and DPF/EGR inspections. We can also run an engine oil analysis on diesel engines — especially valuable for hard-working diesels where wear metals tell you early if injectors or bearings need attention. See our pricing page for diesel oil service tiers starting at $159.99.
