Oil Changes
How often should I change my oil in Florida?
Every 3,000 to 5,000 miles for conventional oil. Every 7,000 to 10,000 miles for full synthetic. Florida heat breaks down oil faster than in cooler climates, so staying toward the lower end of your interval is wise for Lake County drivers.
What type of oil does my vehicle need?
The correct oil type and viscosity is in your owner's manual. We look it up for every vehicle and use exactly what your engine requires. Never guess on oil spec.
What is included with an oil change at AJ Automotive?
Every oil change includes an oil and filter service using the correct specification, plus a multi-point inspection covering brakes, tires, belts, hoses, and all fluid levels. You leave knowing the full condition of your vehicle.
How long does an oil change take?
Most oil changes are completed in 30 to 45 minutes.
What is high-mileage oil and does my vehicle need it?
High-mileage oil is formulated for vehicles over 75,000 miles. It contains additives that condition aging seals, reduce oil burn-off, and minimize wear on higher-mileage engines. If your vehicle is over 75,000 miles it is generally worth the upgrade.
Brakes
How do I know if my brakes need service?
Common signs include squealing or grinding noises, a soft or spongy pedal, the vehicle pulling to one side when braking, vibration through the pedal, or a brake warning light on the dashboard. Any of these is a reason to have the system inspected.
How long do brake pads last?
Typically 25,000 to 65,000 miles depending on driving habits, vehicle weight, and pad material. Stop-and-go driving in town wears pads faster than highway driving.
Do I always need new rotors when I get new pads?
Not always. We measure rotor thickness and check for warping. If they are within spec and not scored, pad replacement alone may be sufficient. We will tell you honestly what your rotors need rather than upselling replacement by default.
How long does a brake job take?
A standard pad and rotor replacement on one axle typically takes one to two hours. Full four-wheel brake service takes two to three hours.
A/C Repair
Why is my A/C blowing warm air?
The most common causes are low refrigerant from a leak, a failed compressor, a clogged condenser, or an electrical fault. We diagnose the specific cause before recommending any repair.
Can I just recharge the A/C myself with a store-bought kit?
DIY recharge cans add refrigerant without finding or fixing the leak that caused the loss. This is a temporary fix at best and often does not address the underlying problem. We find and repair the leak so the charge holds long-term.
How often should A/C be serviced in Florida?
We recommend an A/C inspection every year before summer. Florida A/C systems run harder and longer than in other states and catching small issues in spring prevents a breakdown in July.
How long does A/C repair take?
A recharge with leak inspection takes one to two hours. Compressor or condenser replacement typically takes three to five hours depending on the vehicle.
Check Engine Light
What does a check engine light mean?
It means a sensor detected a condition outside normal parameters and stored a fault code. It could be something minor like a loose gas cap or something more significant like a misfiring cylinder. The code points to a system, not a specific part. Proper diagnosis is required to determine what actually failed.
Can I drive with the check engine light on?
If the light is steady and the vehicle is driving normally, it is generally safe for a short period but should be diagnosed soon. If the light is flashing, reduce speed and have it checked immediately. A flashing light indicates active engine misfires that can damage the catalytic converter.
Will clearing the code fix the problem?
No. Clearing the code turns off the light but does not fix the underlying issue. The light will return if the problem is not repaired. We diagnose and fix the root cause, not just clear the code.
How long does engine diagnosis take?
Initial scanning and diagnosis typically takes one to two hours. Complex or intermittent faults may require additional time.
Tires
How often should I rotate my tires?
Every 5,000 to 7,500 miles, which for most drivers is every other oil change. Florida heat accelerates rubber wear so staying consistent with rotations matters more here than in cooler climates.
What is included with a tire rotation at AJ Automotive?
Every rotation includes the correct pattern for your drivetrain, tread depth measurement on all four tires, a tire condition inspection, inflation adjustment to manufacturer spec, and lug nut torque to specification after reinstallation.
How do I know when my tires need to be replaced?
Tread depth below 2/32 of an inch is the legal minimum in Florida but we recommend replacing at 4/32 for safety in wet conditions. We also look at tire age since rubber degrades in Florida's heat even if tread remains. Sidewall cracking, bulges, and uneven wear are also reasons to replace.
Do you do wheel alignments?
Yes. We perform four-wheel alignment to manufacturer specifications. We recommend checking alignment annually or after any significant impact such as hitting a large pothole or curb. Misalignment is the leading cause of premature tire wear.
Florida & Lake County
Does Florida heat really affect my vehicle differently?
Yes significantly. Heat accelerates oil breakdown, degrades battery plates faster, dries out A/C seals, ages rubber components faster, and keeps cooling systems working at or near capacity during summer months. Maintenance intervals that work in northern states are often too long for Florida vehicles.
How long do batteries last in Florida?
Typically three to four years compared to five or more years in cooler climates. Heat degrades internal battery plates faster than cold does, which is the opposite of what most people assume. If your battery is more than three years old it is worth having it tested.
Does living near a lake affect my vehicle?
Yes. The high humidity near Lake County's many lakes promotes corrosion in electrical connectors and terminals, accelerates rust on brake hardware and exhaust components, and increases the dehumidification load on A/C systems. We factor local environmental conditions into every inspection and service recommendation.
How far do you serve from Eustis?
We are located in Eustis and regularly serve Mount Dora (about 5 miles), Tavares (about 6 miles), Umatilla (about 10 miles), Leesburg (about 12 miles), Fruitland Park (about 13 miles), and Lady Lake (about 16 miles). See our service areas page for more information.
Does Florida require vehicle emissions testing?
Lake County uses an OBD-II emissions inspection program. Your vehicle's onboard diagnostic system is scanned for fault codes and readiness monitors. Any active check engine light is an automatic failure. We can scan your vehicle before the official test and repair any issues so you pass the first time.
