What Motor Oil is Best for Winter? (And Other Cold-Weather Questions) https://hrsynthetics.ca/ Synthetic oil is the best winter motor oil. We’re done here. If only it were that simple. But most people want empirical data to support such claims. Well, take a look at the video. We cooled a conventional 5W-30 motor oil and AMSOIL Signature Series 5W-30 Synthetic Motor Oil to -40º. As you can see, the conventional oil thickened so much that it barely flowed from the beaker. The AMSOIL product, on the other hand, flows almost immediately. Shop AMSOIL Synthetic Motor Oil Why the dramatic performance difference? In answering that question, I’ll also answer the question hoss61761 poses on social media: Conventional oils contain waxes that solidify when the temperature drops. This severely impairs the oil’s ability to flow when you crank your engine. In some cases, the oil can thicken so much that it prevents the crankshaft from spinning fast...

Watch this Two-Stroke Snowmobile Oil Comparison https://hrsynthetics.ca/ We conducted a two-stroke snowmobile oil comparison to see how some of the top snowmobile oils on the market handle -40º temperatures. That’s because oil cold-flow is vital for good wear protection in modern two-stroke sleds. The same demands driving changes in the automotive market are influencing two-stoke engines as well. The government requires reduced exhaust emissions, yet you don’t want any sacrifices in power and fuel efficiency. Play nice, kids What’s a two-stroke engine manufacturer to do? These three areas – reduced emissions, increased fuel economy and maximum performance – don’t play well together. It’s extremely difficult to build an engine that hits all three targets given the constraints of two-stroke engine design. Because they don’t contain intake and exhaust valves like a four-stroke engine, controlling emissions in two-strokes is a big challenge. One strategy...
