At your address — the on-site procedure
What actually happens once the truck arrives. Roughly an hour, start to finish.
Questions, asked & answered.
Most of what people want to know before booking. If yours isn't here, text or call 319 · 330 · 7776
What oil do you use?
Parts Master (Valvoline) oil and WIX oil filters as our standard fill — solid mid-tier brands we trust.
If your manual calls for a specific oil type, weight, or brand (Mobil 1, Pennzoil Platinum, a Euro spec, etc.), tell us in the booking notes and we'll source it. Customer-specified fills cost a bit more, but no markup games.
How long does an oil change take?
About an hour for most cars, start to finish — pulling up, on the ramps, drained, refilled, off the ramps, packed up.
We confirm the actual estimate when we lock in the appointment.
Do I need to be there during the service?
Not at all. If you prepay (Venmo or a Square card link), leave the keys somewhere we can find them and we'll handle everything.
Plenty of regulars never see the truck — we just need a way to reach you if something comes up.
Can you service my RV, truck, SUV, or equipment?
Yes — all makes and models. Standard cars, light trucks, SUVs, heavy-duty diesels, European exotics — we service them all.
RVs and motorhomes are a specialty — we'll come to your storage lot, campground, or driveway. RV pricing depends on the engine and size, and we can service the onboard generator too — a typical gas RV engine runs around $200. We also handle tractors, generators, mowers, and ATVs by quote (see RV & motorhome service). If your vehicle takes a specialty oil or filter we don't stock, we'll source it.
How do you take payment?
Cash, Venmo, and cards via Square. Cash is no-fee and preferred; Venmo carries a 1.9% fee and cards via Square a 3% fee.
Payment is due when the service is completed, or in advance if you'd like us to service the vehicle while you're not home.
What if I need to cancel or reschedule?
No cancellation fee with more than 24 hours' notice. Life happens — just let us know.
Full cancellation policy is on the Terms page.
My driveway isn't flat / I rent / I park in a garage. Can you still service it?
We can work almost anywhere — driveways, parking lots, surface lots, apartment complexes, even most parking garages.
The only real deal-breakers are steeply sloped driveways where the ramps can't sit level, or very low-clearance garages where the truck won't fit. If you're unsure, mention it when you book and we'll figure it out.
If you park on someone else's property — an employer lot, apartment complex, storage lot, HOA-managed driveway — we'll need a heads-up from the property owner or manager before the appointment. We don't ring strangers on your behalf.
Can you service my car at work or my apartment complex?
Usually yes — we work at employer parking lots, apartment complexes, storage lots, and HOA-managed driveways all the time.
Heads-up though: if you park on someone else's property, you'll need to clear the appointment with the property owner, manager, or HOA first. We don't call strangers on your behalf. Once they're OK with it, we're good to roll.
Where does the used oil go?
Recycled — locally. The used oil from your engine goes into a recovery tank in the truck. We hand it off to BJ's Towing & Recovery in Williamsburg, which runs a waste-oil furnace and heats their building through Iowa winters.
Same outcome, smaller chain of custody — no oil down a drain, no oil to a landfill. Filters are drained and properly disposed of through licensed channels. We hold the permits required to collect and transport used oil from your address.
How do I know it's time for an oil change?
Modern vehicles usually tell you — most have an oil-life percentage on the dashboard. As a general rule: conventional every 3,000 miles, synthetic every 5,000–7,000 miles. Severe-duty conditions (towing, dust, lots of short trips, Iowa winters) shorten that.
We'll leave a windshield-corner sticker with your next-change mileage when we're done.
Do you do other auto repair?
We focus on routine maintenance — oil changes, filter swaps, fluid services, wiper blades, tire-pressure checks, and washer-fluid top-offs. We don't do engine work, transmission rebuilds, or anything requiring a hoist.
If you need that, we can usually recommend a shop in the area.
Do you do brakes?
Pads and basic brake jobs — case-by-case. If we can do it safely from ramps and your car's a fit, we'll quote it. If it needs a hoist or rotor work, we'll pass and recommend a local shop.
We top off brake fluid as part of Fluid service — top-offs only, no flushes.

One truck. One operator.
"If I'm doing your oil, I'm the one answering the phone when you call back. Same hands, same number, every time."
Started in 2020 with one truck, one set of ramps, and a phone number my customers still call. Six years later it's still me on the wrench. No corporate scheduling, no upsells on filters you don't need.
Reviews from Williamsburg-area drivers.
"Josh is very friendly and helpful. He is flexible with scheduling and has gone out of his way to help with special requests. He's always neat and never leaves any mess behind. We highly recommend!"
"Great service and convenience."
"Fast, efficient and convenient!"
From the truck — things worth knowing.
Short reads on what we use, how often you actually need a change, and where the used oil ends up.
Synthetic, semi-synthetic, or conventional?
Conventional is fine for older engines and short commutes — change it every 3,000 miles. Semi-synthetic (a blend) handles temperature swings better and stretches intervals to about 5,000 miles. Full synthetic goes 5,000–7,000 miles and protects better at startup; most newer cars are spec'd for it.
We stock Parts Master (Valvoline) across all three. If your manual calls for something specific — Mobil 1, Pennzoil Platinum, a Euro spec — we'll source it for an upcharge.
How do I know it's time?
Most cars built after about 2010 have an oil-life percentage on the dash. When it hits 15%, plan the change. Get it scheduled before it reaches 5% — don't wait for 0%.
Don't have a percentage? The old rules still work: 3,000 mi on conventional, 5,000–7,000 mi on synthetic. Trucks and tow vehicles change sooner.
We leave a windshield-corner sticker with your next-change mileage every time.
Where the used oil actually goes.
Every drop we drain goes into a recovery tank in the truck. We hand it off to BJ's Towing & Recovery here in Williamsburg, which recycles it and burns it for heat in a waste-oil furnace — the same oil that lubricated your engine now warms a Williamsburg-area building through Iowa winters.
Filters are drained and disposed of through licensed channels. Same outcome as a shop visit — no oil down a drain, no oil to a landfill — just without you driving anywhere. We hold the permits required to collect and transport used oil from your address.
