Do Additives Hurt Your Engine?

July 17, 2023 · 2 min read

Fuel additives can seem helpful in reducing your need for maintenance, but they can harm as much as they help. By thickening the fluids they’re added to, they can lead to severe issues or interfere with your engine’s sensors. Instead, come down to Rick Weaver GMC and have our team perform GMC service for the best performance.

Fuel Additives Can Hurt Your Engine

Engines are complex, especially on newer models, and differ in many important ways. A fuel additive that may provide minor benefits on certain types of engines, usually those in older models, may cause issues with the more complex designs favored in newer models. In addition to potentially thickening your fluids, which can lead to clogs and other serious problems, fuel additives can affect gauges and other sensors, leading your vehicle to fail to detect problems or alert you to issues that do not exist.

Fuel Additives May Not Work

Your car isn’t a lab rat; it’s a complex piece of machinery. If you're preserving performance, there’s no place for placebos, so why take your chances on an additive that might not work?

On some systems, additives may do nothing at all, while on others, they may provide a temporary benefit only to be quickly flushed out of the system. In addition, fuel additives working properly only limit future buildup, so if you’ve noticed an issue, adding one will not fix the underlying cause. A complete tune-up is a much more efficient way of keeping your vehicle running at its best.

2026 GMC Sierra 1500 vs GMC Canyon: Which Truck is Right for You?

There is so much to love about every truck in the GMC lineup. As a GMC Sierra dealer, we often have buyers ask if they should get the full-size truck or consider the midsize GMC Canyon. Rick Weaver GMC outlines each option. Power The 2026 GMC Canyon uses a TurboMax™ 2.7-liter turbocharged four-cylinder engine to deliver up to 310 horsepower and 430 lb-ft of torque. The GMC Sierra 1500 also comes with the same robust engine. However, it’s available with three additional options if you want even more power: 5.3-liter V8 engine: 355 horsepower and 383 lb-ft of torque Duramax® 3.0-liter turbo-diesel engine: 305 horsepower and 495 lb-ft of torque 6.2-liter V8 engine: 420 horsepower and 460 lb-ft of torque Capabilities If you need serious towing power, the 2026 GMC Sierra 1500 is the better fit. With the available turbo-diesel engine, it can tow up to 13,300 lbs when properly equipped. The GMC Canyon also has a notable 7,700-lb max towing capacity. Size As a midsize truck, the 2026 GMC Canyon is quite a bit smaller than the full-size GMC Sierra 1500. While it's still powerful, its smaller size makes it more fuel-efficient. The midsize truck is also easier to maneuver and park. If you prioritize efficiency and agility, consider the GMC Canyon. Off-Road-Ready Both of these trucks are adept for off-road adventures. However, some drivers prefer a smaller size when they’re off-roading, because it can be easier to get through tight spots and trails. They also have a tighter turning radius and better angles. That could make the 2026 GMC Canyon a better fit for drivers who leave the road behind. Explore Our New GMC Trucks in Erie, PA Each of these GMC trucks are excellent options. You just have to decide what you need out of your next truck. Visit Rick Weaver GMC to explore both models and compare them with a test drive!
