"Amazing group here. Very dedicated to providing an excellent experience, and excellent result. They go above and beyond to satisfy their customers. You can't do better than these guys. If you're looking for the best deal, the best work, and the best experience, look no further."
"It is such a relief to have my vehicle back in working order - especially after neglecting maintenance for far too long after the only shop I trusted sold their business. Like a lot of women, I hate the typical experience at a shop, and am glad I gave Kriegers Repair a shot. Nothing is cheap these days but the rate was fair and the work was completed quickly and to my satisfaction. I appreciate the time and work that John did and will be recommending him to family and friends."
"John is one hell of a dude i ran out of battery here is bennett colorado i came up to him to ask if he could help out, right away got to it and helped me out to get my car started he awesome i recommend!!!"

Diesel engines typically require regular maintenance every 10,000 to 15,000 miles or as recommended by the manufacturer. Essential tasks include oil changes, air and fuel filter replacements, and system diagnostics. Staying proactive with preventive maintenance helps avoid costly repairs and prolongs engine life.
Diesel engines may struggle to start due to issues like a weak battery, faulty glow plugs, or low fuel pressure. Other potential causes include a clogged fuel filter or air intake problems. Regular maintenance can help identify and resolve these issues before they worsen.
Diesel engine oil should typically be replaced every 5,000 to 7,500 miles, depending on driving conditions and manufacturer recommendations. Frequent towing or operating in extreme temperatures may require more frequent oil changes. Always use oil specified for diesel engines for optimal performance.
