Why Do I Get Worse Diesel Mileage in the Winter?

Why does your diesel gas mileage go down in the winter? One reason is the composition of winter diesel makes it more volatile to burn properly in cold weather conditions.  Just like with gasoline, refiners have to change the composition of diesel fuel in the winter to help it function better in the cold weather.  But this change has much less to do with “volatility” and more to do with both cold gelling performance and sulfur reduction.

Typically, winter diesel will have about 3% less energy value. That’s because some of the Sulphur is removed. Lower energy value means less miles per gallon.

During the winter months, refiners mix in additional additives in order to change the properties of the winter diesel so that its gelling temperatures are reduced. With Canadian extreme winters, refiners want to give a little more temperature margin when it comes to how quickly the diesel fuel will gel in cold weather.

To minimize the effect of reduced mileage in the winter, keep your diesel in tip top condition with regular maintenance at Western Turbo.  When it’s time for the best diesel service in Winnipeg, the biggest parts selection or turbocharger diagnostics, give us a call at 1 800 665 7556 or send us an email to info@westernturbo.com

Winter’s coming – Here’s Some Tips to Make Sure Your Truck is Ready

Winnipeg winters are especially tough on trucks!

From overnight cold soaks as low as -40, to icy roads, spray from slush, to blowing snow and snowdrifts, we see it all. To see you and your truck through the season with minimal downtime, there are a some basic checks and tests that can save you time and money by identifying issues before they become a problem.

  • First inspect the tires for tread depth and proper inflation, remember tire pressure is affected by ambient temperature. Be sure to inspect the sidewall condition, and verify all lug nuts are correctly torqued.
  • Verify proper oil levels on front axle, transmission, transfer case, rear axle, and power steering as required.
  • Check windshield washer fluid is rated for winter use, and replace if not.
  • Perform a walk around inspection, checking all lights.
  • Test block heater and cord, and inspect air filter condition.
  • This is the right time to service the engine with a proper winter grade oil, and lubricate the chassis.
  • Top up DEF as required.
  • Carefully inspect the belts and coolant hoses for cracks and overall condition.
  • Check batteries are properly secured, and inspect cables and connections. If in doubt about battery condition, perform a load test.
  • Test coolant strength and verify adequate additive protection levels with a test strip. In the cab, inspect the cabin air filter, if more than a year old, you should replace it.
  • Check that all defrost/ vent/ heat settings operate correctly, and check that fan operates at all speeds. Make sure heater control valve opens properly.
  • Consider a box of emergency supplies suitable for our climate, particularly if you travel on the highway, or infrequently traveled roads.
