Warming Up Your Car: Good for You, Bad for Your Engine

Not long ago, Popular Mechanics posted an article about something we tell our customers all the time (and most don’t believe us): warming up your car by letting it idle when cold out certainly helps your car get comfy, but it’s bad for modern engines. In fact, the method that we all use today originated back when engines were carbureted and is completely outmoded today. Says Popular Mechanics:
Warming up your car before driving is a leftover practice from a time when carbureted engines dominated the roads. Carburetors mix gasoline and air to make vaporized fuel to run an engine, but they don’t have sensors that tweak the amount of gasoline when it’s cold out. As a result, you have to let older cars…

Older Engines and Zinc (ZDDP): What You Need to Know

It’s no secret that older engines aren’t like today’s modern computer-controlled powerplants. In particular, high-performance older engines (like those in classic cars and hot rods) have lubrication demands that are not met by modern oils.

That demand, in a word, is zinc dialkyldithiophosphate, otherwise known as ZDDP. We’ll come back to that in a second.

But first, why are modern oils lacking ZDDP protection?

It’s a simple story of market evolution: over the years, motor oils have been updated to meet the needs to changing engine designs. While that’s great for newer motors, it leaves older engines out in the cold. These updated oils have greatly reduced ZDDP levels, so they simply do not offer the protection needed for older engines.

So then. What is ZDDP anyway, and…

Rislone at the GoPro Mountain Games in Vail, CO

Not too long ago, Rislone attended the GoPro Mountain Games in Vail, Colorado. The event was everything you’d think a GoPro event in the mountains would be: energetic, daring and full of people who drove hundreds of miles to attend. Rislone was a featured brand, and people loved our Rislone Complete Fuel System Treatment, which we gave away to those who stopped by our booth to chat. Bobby Janiec and Caitlin Burt, the Rislone spokesteam, were swamped, but swamped by cool people who know how to have fun is never a bad thing.

What’s a picture worth? A thousand words. What’s a video worth? Probably a million, which means we’re sparing you a lot of text by showing you this video…

Rislone Ring Seal Smoke Repair Makes Marriage Happy Again

We got a LOT of customer emails and testimonials, but this one takes the cake. In it, Richard H. from Memphis, TN talks about how Rislone Ring Seal Smoke Repair (p/n 4416) made his home happy again after a mower incident. Here’s what Richard writes:
While in the hospital my wife loaned my new craftsman 20 hp. lawn mower to a friend. After I returned home I started my mower and I almost choked with smoke. I have no idea what she did? I was not happy. I reminded her that I never loan tools to anyone, which she already knew!

I was replacing plugs and adding oil non stop. I used your product (ring…

Rislone Tech Minute: Rislone Engine Treatment

Here’s a quick overview of Rislone Engine Treatment (p/n 100QR), a bestselling product for 91 years and counting. The formulation has changed as oil technology has advanced, but the results haven’t.

Rislone Engine Treatment is a high quality penetrating lubrication oil, combined with protective engine additives and unique cleaning additives. Its multi-grade formula allows the oil to flow freely and provides protection over a broader temperature range. The unique Rislone Formula is designed to penetrate into valve seats, bearing surfaces, piston rings and ring grooves, where deposits are likely to form. These deposits are gradually removed and held in suspension until they are trapped in the filter or removed with the next oil change.
