Oil Service

What an Oil Change at Hamiltons Actually Covers Actually Covers

An oil change is a 15-minute decision that protects an engine worth thousands.

  1. 01

    Correct oil specification

    We match the oil weight and type to your vehicle's actual spec, not a generic shelf choice.

  2. 02

    Filter and seal inspection

    A fresh filter does nothing if the drain plug seal is worn. We check both before the car leaves.

  3. 03

    Fluid level sweep

    Coolant, brake fluid, transmission fluid, and power steering get a visual check every visit.

  4. 04

    Interval planning

    We'll tell you where you are on your 30k, 60k, or 90k service so you're not caught off guard.

Diagnostics

Check Engine Light On Near Novato

A check engine light is not a death sentence and it's not always something you can ignore. Our diagnostic center runs multi-system scans covering engine codes, ABS faults, and emissions issues. We explain what the scan found in plain language before any work starts.

  1. 01

    Plug in and scan

    We connect to your vehicle's OBD system and pull every stored code across all monitored systems, not just the powertrain.

  2. 02

    Interpret and explain

    Leo's team walks you through what the codes mean in real terms. No jargon, no pressure to approve everything at once.

  3. 03

    Repair in sequence

    We prioritize the issues that affect safety and drivability first, and we let you decide how to proceed on the rest.

My oil change light came on as I was driving to a client meeting in Novato. I stopped by Hamiltons Automotive after talking to Leo, the owner, on the phone. The team was helpful and even recommended a tire realignment. They got me out of there quickly and provided a great service.

Hamilton Automotive is FAMILIA! SO GLAD I found this place. Hamilton Familia has been taking care of all my autos exclusively for 6yrs, 2 Toyotas, 2 Fords a Hyundai SF, and an Audi. They get you on the road and keep you there, call with estimate, go over your service, service the whole car, keep up on regular maintenence. I'm singing their praises when I drive. After my last repair car had sensation it was going to take off flying, I thought, I guess it's running pretty good. Take a chance on Hamilton you'll keep coming back. Big Thank You to everyone there.

Beyond Oil Changes: Full Repairs at One Location

01

Brake Repair

Pads, rotors, calipers, and brake fluid service handled in-house. If your car is pulling to one side or the pedal feels soft, don't wait.

02

Transmission Service

From fluid changes to full rebuilds, we handle transmission repair without subcontracting. Big repairs need someone accountable.

03

Shocks and Struts

Novato roads and the 101 on-ramp washboard wear suspension components faster than most drivers realize. We inspect and replace shocks and struts as needed.

04

AC Repair

When the AC stops blowing cold in the middle of a North Bay summer, we diagnose and recharge or repair the system the same week in most cases.

Frequently asked questions

How close is Hamiltons Automotive to downtown Novato?
The shop is at 1032 First Street, which puts it right in the heart of Novato's main corridor. If you're coming from the Hamilton neighborhood or the Grant Avenue area, you're looking at a five-minute drive. Customers coming off Highway 101 at the Rowland Boulevard or San Marin exits can reach us in under ten minutes in normal traffic. It's a straightforward stop before or after work.
How often do Novato drivers actually need an oil change?
Most modern vehicles are designed for oil changes every 5,000 to 7,500 miles on conventional oil, or every 7,500 to 10,000 miles on full synthetic. If you're doing a lot of stop-and-go driving on Highway 101 through Novato or making short trips around town, the lower end of that range is the safer call. Short-trip driving doesn't fully warm the engine, which means oil breaks down faster. We check your vehicle's actual spec and recommend accordingly.
Can I get a tire alignment at the same visit as my oil change in Novato?
Yes. Grayson Phillips, a Novato customer, came in for an oil change and we recommended a tire alignment the same visit. Combining services in one stop is exactly how the shop is set up. If you're noticing uneven tire wear or the car drifting on the 101, it's worth getting the alignment checked while you're already here. We handle both without sending you to a different shop.
What's included in Hamiltons Automotive's scheduled maintenance for 30k, 60k, and 90k services?
Each interval covers a different set of components based on your manufacturer's schedule. The 30k service focuses on filters, fluids, and a full system inspection. The 60k goes deeper into the transmission fluid, coolant, and brake system. By 90k we're looking at spark plugs, the throttle body, and a detailed drivetrain review. We don't guess at what your vehicle needs. We pull the actual maintenance schedule for your make and model and go from there. Contact us at 415-898-4842 to discuss your vehicle's current mileage.
Does Hamiltons work on trucks and motorcycles in addition to cars in the Novato area?
Yes, and that's one of the reasons Novato customers keep coming back. Most local shops handle passenger cars and stop there. We work on cars, trucks, motorcycles, and golf carts at the same location. Jordan Jumpshot has been bringing multiple vehicles here for six years, including Toyotas, Fords, a Hyundai, and an Audi. If you've been bouncing between specialists, one call to 415-898-4842 covers most of what you need.
What should I do if my check engine light comes on while driving in Novato?
Don't ignore it, but don't panic either. A check engine light covers a wide range of codes, from a loose gas cap to a misfiring cylinder. The only way to know is a proper scan. Bring it to our diagnostic center on First Street and we'll pull the codes, explain what they mean, and tell you which ones need immediate attention and which can wait. We don't start repair work without walking you through the findings first.
