Reviso el kilometraje en el odómetro del auto compacto.

Reviso is the first-person singular present tense of revisar.

• revisar = to check, inspect, look over, review
• reviso = I check / I inspect / I look over

So the sentence is from the speaker’s point of view: I check the mileage...

Spanish often uses the simple present where English also uses the simple present.

In Spanish, subject pronouns are often omitted because the verb ending already shows who is doing the action.

• reviso clearly means I check
• So yo reviso and reviso both mean I check

Including yo is possible, but it usually adds emphasis or contrast:

• Yo reviso el kilometraje... = I’m the one who checks the mileage...

Without emphasis, leaving out yo sounds more natural.

Not usually. This is a very common false friend.

In Spanish, revisar often means:

• to check
• to inspect
• to look over
• to examine

So in this sentence, reviso means I check, not I revise in the English sense of editing or rewriting.

Depending on context, English revise is often better translated as:

• revisar = review/check
• corregir = correct
• modificar = modify
• repasar = review/study over

Kilometraje means mileage or distance recorded in kilometers.

It is a masculine noun, so it takes el:

• el kilometraje

Even though English often uses mileage without an article, Spanish frequently uses the definite article with nouns like this when referring to a specific thing being checked:

• Reviso el kilometraje = I check the mileage

Yes, kilometraje is based on kilómetro, so it normally refers to mileage in terms of kilometers.

In practice, though, it can also refer more generally to a vehicle’s accumulated distance reading, especially in places where kilometers are the normal unit.

If you are talking about Latin America, kilometraje is very natural because most countries use kilometers.

En el odómetro means on/in the odometer and focuses on where the mileage is seen or checked.

• revisar el kilometraje en el odómetro = to check the mileage on the odometer

If you said del odómetro, that would mean of the odometer, which changes the relationship and sounds less natural here.

The sentence is basically saying: I check the mileage as shown on the odometer.

Because de + el contracts to del in Spanish.

• de el auto → del auto

This contraction is required in normal Spanish.

The only common exception is when el is part of a proper name, for example:

• de El Salvador — no contraction

But here el is just the article before auto, so del auto is correct.

All can mean car, but usage varies by region.

In much of Latin America:

• auto = car
• carro = car in many countries
• coche = common in Spain, but less common in many parts of Latin America

So auto is a good neutral Latin American choice.

Depending on the country, people might naturally say:

• el auto
• el carro

Both can be correct regionally.

In Spanish, adjectives often come after the noun.

• auto compacto = compact car

That is the normal order for a descriptive adjective here.

Putting the adjective after the noun is the most straightforward and common structure:

• un auto compacto
• un carro compacto

Not naturally in ordinary Spanish. Auto compacto is the standard order.

Adjectives before the noun in Spanish often sound more literary, emphatic, or may slightly change the nuance. In this case, compacto normally goes after the noun.

So:

• el auto compacto = natural
• el compacto auto = unusual or unnatural in everyday speech

Yes, odómetro is the normal word for odometer.

It has a written accent because the stress falls on dó:

• o-DÓ-me-tro

Without the accent mark, the pronunciation rules would suggest a different stress pattern, so the accent is needed.

Also notice that many technical words in Spanish use accent marks even when their English equivalents do not.

Yes. Some alternatives are:

• verifico el kilometraje = I verify the mileage
• compruebo el kilometraje = I check/confirm the mileage
• checo el kilometraje = I check the mileage

A few notes:

• verificar sounds a bit more formal
• comprobar is common and standard
• checar / chequear are widely used in parts of Latin America, but they are more colloquial and regional

Reviso sounds very natural and neutral in this sentence.

Yes, it is understandable and generally natural. It sounds a bit careful or textbook-like, but still correct.

A more everyday version in some countries might be:

• Reviso el kilometraje del auto en el odómetro.
• Checo el kilometraje del carro.
• Veo el kilometraje en el odómetro.

Your original sentence is perfectly fine, especially for learning standard vocabulary.

A rough pronunciation guide is:

reh-BEE-so el kee-loh-meh-TRAH-heh en el oh-DOH-meh-troh del OW-toh kom-PAHK-toh

A few useful pronunciation points:

• r in reviso is a light tapped r
• j in kilometraje sounds like a strong English h
• d in odómetro is softer than English d
• vowels are pure and short compared with English:
  • a = ah
  • e = eh
  • i = ee
  • o = oh
  • u = oo

Yes. Kilometraje can refer both to:

1. the current mileage reading, and
2. a vehicle’s mileage in a broader sense

For example:

• El auto tiene mucho kilometraje. = The car has high mileage.
• Reviso el kilometraje en el odómetro. = I check the mileage on the odometer.

So the exact nuance depends on context, but in your sentence it clearly refers to the reading being checked.
