What Fluids Should I Service Regularly?
Engine oil, coolant, transmission fluid, brake fluid, and power steering fluid should all be checked regularly. Replacing them on schedule protects your truck from wear and overheating.
How Often Should I Change My Truck’s Oil?
Oil change intervals vary by engine type and usage, but most trucks benefit from a change every 10,000 to 25,000 miles. Frequent short hauls or extreme loads may shorten that range.

Saying About Us
See why our customers consider 509 Roadside their go-to repair shop in Moses Lake, WA and the surrounding areas!
These guys came out and did a roadside repair on my trailer and got me patched up in no time, their mechanic even followed me to my destination to make sure everything went smoothly. They went above and beyond, excellent and professional service. Thanks guys!
Joseph helped me out when my car couldn’t shift gears coming from Spokane, going back to Western WA. It was 99 degrees out and he came from his house to help me. He was calm, knowledgeable, communicated well, and honest. He even called me when I got back home to make sure I made it and gave me some car tips. There aren’t too many people out there like him. I believe in karma, and Joseph deserves all the best karma his way.
509 Roadside is amazing. I was driving my truck and was in the area with an airbag broken on my trailer. I called 7 different shops within 100 miles of Moses lake around 1pm on a Thursday 3/13/25 and 509 was the only one to answer. Not only did they answer but they took the time to find the correct airbag and get me safely back on the road at a very reasonable price! It was a great experience and I will definitely be using their services again if I’m ever in need.
Came in for an issue, fixed extremely quick. The most honest mechanics ive seen in a long time. Will definitely be coming back for any future issues!
Joseph did a great job replacing a small engine for us. He searched, bought and replaced it for us while keeping us informed every step of the way. With great pricing and service, we will continue to utilize him in the future for our needs.
These guys got me in to their shop on short notice and found my electrical problem quickly. Can’t thank them enough! I will call them again if I need help in the area!!
509 Roadside saved my day. I locked my keys in my trunk and called insurance to have them help connect me with someone to get into my car. I was waiting for the maintenance truck to come, 2.5 hours after my call. 509 Roadside was just driving by and helped. Super nice guy!
Had issue with semi shutting down due to coolant level issue, contacted 509 to assist and they were earlier then expected, very friendly and got me back on the road quickly and went beyond duty and even checked other things to prevent any other issues. Would call them first if I ever have a problem down road.
