# Guides

These guides answer the questions behind the services: how often to change oil, what a failed smog check means, what the altitude and the Tahoe trips do to a car. Each one is written answer-first, cites its sources, and ends with what to do at the service center.

★★★★★ 4.7 stars from 952 Google reviews

A guide here is the long version of the conversation at the window. The short version is "your filter is dirty, want it changed?"; the long version explains why a high-desert climate with about seven inches of rain a year clogs filters faster, what the Car Care Council says about intervals, and how to tell when it is really due. Read them before you come in, or afterward when you want to understand what the technician showed you.

## What is here

Each guide shows its reading time and the date it was written. Where a guide gives a number, the source is in the same sentence or at the bottom of the page: AAA, the Car Care Council, the American Petroleum Institute, the Nevada DMV, NOAA climate normals or the manufacturer's manual. Where the answer is "it depends on your car", the guide says so and tells you where in the manual to look.

- Oil: [how often to change oil](https://xpressoilandlube.com/guides/how-often-to-change-oil/), synthetic versus conventional, miles versus months, the first oil change on a new car, reading the oil cap
- Smog: the [Nevada smog check guide](https://xpressoilandlube.com/guides/nevada-smog-check-guide/), what to do after a failed test, the check engine light, registration renewal steps, moving to Nevada
- Seasons and terrain: [winter prep](https://xpressoilandlube.com/guides/winter-car-prep-reno/), summer heat, high-altitude driving, towing, dusty roads
- Fluids and parts: transmission fluid color, coolant types, A/C recharge, wipers, headlight bulbs, batteries in the cold, the oil filter, the maintenance check
- Fleet: a maintenance plan for work vehicles

Read the one that matches your question, then bring the car in and ask the technician to show you.
