You work hard all week, so by the time the weekend rolls around, there’s no place you’d rather be than behind the wheel of your classic or collector car. But what if when you turn the key in your ignition there’s a loud clicking noise that causes your heart to sink as you realize, these tires won’t be hitting the pavement today?

That clicking noise that replaced the rev in your engine can be caused by the build-up of rust. There are a number of causes for rust build up. For classic and collector cars, the most common cause is letting them sit in the garage for long periods of time. Rust can not only ruin your weekend plans, it can also cause less engine reliability overall. To help you better understand the causes and effects of rust in your engine, Kendall Motor Oil partnered with industry engineers to compare four of the leading high-mileage motor oils, including Kendall GT-1â Endurance with rust fighting additives. In the end, GT-1 Endurance proved to offer rust protection that outlasted the rest for an additional 1,000 miles.

To get you familiarized with the sound of a rusty engine — without rusting your own precious metal — we built a GT-1 Endurance Rust Demonstration comparing the sounds of a rusty engine and an engine protected by GT-1 Endurance. We also developed new information to help drivers recognize a rusty engine and ways to avoid rust in your own engine.

The most important takeaway from all of this: GT-1 Endurance prevents rust. If you’re able to make it to the Kendall Motor Oil booth at a Mecum Auction this year, stop by and give the GT-1 Endurance Rust Demo a try. If an auction isn’t in the cards this year, you can still view the test results and gather more information on rust and corrosion — and how to prevent it — at:
