Question 3

When should I change my oil?

Accepted Answer

Most vehicles need an oil change every 3,000–5,000 miles or every 3–6 months, depending on the type of oil used and driving conditions. Older vehicles may require more frequent changes, especially if they experience heavy use or extreme temperatures.

Question 4

What does a check engine light mean?

Accepted Answer

A check engine light could signal anything from a minor issue to a major repair. While auto parts stores can provide Diagnostic Trouble Codes (DTCs), these only point to the problem area, not the exact cause.
At 21 Machine, we use advanced diagnostic tools to pinpoint the exact issue and recommend the right fix, saving you time and money. Don’t guess—let us handle it for you.

When should I replace my tires?

Accepted Answer

Regular tire checks are essential for safety. Replace your tires if you notice:
Worn-out tread or bald spots.
Cracks or bulges in the sidewalls.
Uneven wear patterns or vibrations while driving.
Embedded nails or objects.
We can inspect, repair, or replace your tires and ensure proper tire balancing and alignment to keep you safe on the road.
