This is a 2019 RAM, 1500 limited  and it is the newest full-size pickup truck on the market. It'S also the most luxurious. This one has a sticker price of a shade over $ 65,000, which is an enormous amount of money for a truck that isn't a heavy duty or Super Duty model. Today, I 'm going to take you on a tour of it . I'Ve borrowed this Ram 1500 from a ram of ontario here in Orange County California, where they have a wide selection of new Rams and all sorts of different colors and trim levels and body styles.

Car Fluids Guide: Oil, Coolant, ATF and Brake Fluid, and Which Ones You Can Mix

Modern cars depend on half a dozen specialized fluids, and each one is engineered for a specific job and chemistry. Topping up with the wrong one is one of the most common and most expensive DIY mistakes: the wrong coolant can corrode an aluminum radiator, the wrong transmission fluid can ruin a CVT, and silicone brake fluid in the wrong system can damage seals. This guide covers what each fluid does, how to read the specifications, how to check levels, typical change intervals and which fluids are compatible with each other. Full-size SUV parked on a lawn in front of a brick building Key takeaways Always match the specification in your owner's manual, not just the viscosity or the color. Current gasoline engine oil standards are API SQ and ILSAC GF-7, first licensed on March 31, 2025. Coolant color is just dye. Match the chemistry (OAT, HOAT, P-HOAT, Si-OAT) your engine requires. DOT 3, DOT 4 and DOT 5.1 brake fluids are glycol-based and compatible; DOT 5 is silicone-based and m...

  • Facts backed by credible sources — standards bodies, government agencies, manufacturer documentation or peer-reviewed research — linked in the text.
  • No spun, scraped or mass-produced machine-generated text. Write from experience; we can tell.

Sponsored posts and paid placements

We accept a limited number of sponsored articles from brands that are relevant to our readers. Sponsored content must meet the same quality bar as everything else we publish. It is clearly labeled Sponsored, and every paid link carries rel="sponsored" in line with Google's guidelines — this protects our readers and keeps both your brand and our site in good standing. We do not sell "dofollow" links. Rates are available on request.

How the process works

  1. Pitch. Send a working title, a 3–5 point outline and a line about your experience through the contact form.
  2. Review. Our editors check fit, originality and reader value, usually within five business days.
  3. Draft. Once approved, send the full article (Google Doc or Word file) within the agreed timeframe.
  4. Edit and fact-check. We may edit for accuracy, clarity, length and style, and we'll ask you about anything we can't verify.
  5. Publish and share. We publish, notify you and keep the article updated over time.
