The best thing you can do to warm up your diesel engine—after letting it idle for no longer than two minutes—is to start driving it. Heading off at a steady pace will heat up the engine and get the oil circulating.
Modern diesel vehicles have better cooling systems than those of old and are designed to warm-up the vehicle quickly. Letting the vehicle start and idle for a minute or two will not hurt it and will only help but much more than that is really unnecessary in my opinion.
Do diesel cars take longer to warm up?
Diesel engines do take longer to warm up than their gas-powered equivalents, but this is down to diesel engines being larger than gas engines rather than the different fuels. Diesel engines tend to be bigger with a heavier block, thicker rods, etc.
How do you warm up a diesel engine in the winter? – Related Questions
Do diesel engines run better in cold weather?
Myth #2: Diesel engines won’t start in the winter.
“Today’s technologies for cold-start are very effective,” Ciatti said. “Modern diesel engines start in cold weather with very little effort.” The problem is that diesel jells at low temperatures. Below about 40°F, certain hydrocarbons in diesel turn gelatinous.
How long does a diesel engine need to warm up?
As a general rule of thumb, if it is below zero degrees Fahrenheit, you should allow your engine up to seven minutes to warm up. If the temperature is between zero and fifty degrees, the warm-up period should be three to five minutes. Over fifty degrees will only require one or two minutes to warm up.
Why do diesels run cooler?
Leaner Air-Fuel Ratio
Lean out the fuel and the engine runs cooler. Add fuel to the mix and combustion temps and exhaust gas temperature goes up. This is why diesels run a leaner air-fuel ratio than gas engines. In fact, some diesels utilize an air-fuel ratio as high as 90:1 or 100:1 at idle.
Should you drive a diesel hard?
A hard driven diesel burns the soot that both hard & soft driving generate but which only hard driving will burn up leaving it to cause damage in a gently driven car. 3. It is about turbo boost. An small engine with lots of boost produces more soot than a bigger less boosted engine producing the same power.
Diesels fitted with a Diesel Particulate Filter (DPF) need regular long runs, some of which must be at high engine speed to clean (regenerate) the filter so are not suited to mostly short, local journeys.
Do short trips hurt diesel engines?
Short trips do not let the diesel engine get warmed up well enough to remove deposits and keep carbon from accumulating and being burnt off. That’s all really. You need at least 15-20 minutes of loaded running to get it to temp and say about 1 hour straight a month of highway driving minimum to keep it all happy.
Do short journeys damage diesel engines?
If you only ever use your car for quick trips, the DPF may not reach the temperature needed to regenerate, causing a blockage that could lead to a breakdown. So, if you drive a diesel, you should always make sure to take longer journeys every so often to keep your DPF clean and in good working order.
What are the disadvantages of a diesel car?
Cons of diesel cars

Is it worth buying a diesel car in 2022?
Put simply, you should buy a diesel car if you regularly cover a lot of high-speed miles, i.e. a regular motorway commute rather than lots of short trips. Diesel cars give better fuel economy than their petrol counterparts, as well as offering more torque on tap for those who want to tow or the like.
But an amazing fact is that diesel engines can run for 1,000,000-1,500,000 miles before needing any major diesel repairs. If kept well-maintained, a diesel engine can be driven for about 30 years or more.
Can you still drive a diesel car after 2030?
Can I still buy a second-hand petrol or diesel car after 2030? Like the above, the ban only affects the sale of new vehicles, so you’ll still be able to buy and sell used petrol or diesel cars after 2030. For the same reason, you’ll also be able to buy and sell used hybrids after 2035, too.
Will diesel cars lose value?
As a current owner of a diesel car, the resale car value is obviously important. When it comes to selling your car, you want to get the best price as easily as possible. And if you’re looking at car valuations, prices of second-hand diesels have definitely fallen.
Is petrol still available after 2040?
What happens to cars after 2040? You will still be able to drive a petrol or diesel car following the ban in 2040. The restriction only affects new cars registered after that date. Cars registered after 2040 will have to be 0 emissions vehicles.
Is there a diesel shortage 2022?

Why are diesel prices higher than gas?
There are three primary reasons for the price discrepancy: the transition to cleaner diesel blends, higher state and federal taxes, and diesel’s supply and demand.
