There are many great things to say about the Chevrolet Duramax Diesel engine. It is smooth, efficient and powerful. But with great power comes great oil consumption. Is the amount of oil that the 2023 Chevy Silverado Duramax burns normal or excessive?
Is the 2023 Chevy Silverado Duramax burning excessive oil?
Some 2023 Chevy Silverado Duramax diesel drivers are concerned that their trucks are burning oil at an excessive rate. However, Pickup Truck Talk noted that the new Duramax diesel engine may require more oil for towing and longer trips.
They have driven their diesel truck for about 5,000 kilometers and already needed two quarts of oil. But its use included a 1,000 mi road trip that involved towing a light load for parts of the trip.
General Motors shared that the LZo diesel engine has an acceptable oil usage rate with a range of one quart per 2,000 miles. You may need more oil if you tow regularly or drive at higher speeds.
Technical Service Bulletin (TSB) 21-NA-272 begins that the accepted oil consumption rate is one quart per 2,000 miles for under-warranty personal use trucks, driven non-aggressively, maintained according the calendar and conducted according to legal regulations. downloaded speeds.
It also mentions that you don’t need to check the oil until you reach 5,000 miles. Also, engines require a break-in period, so the moving parts are well positioned. Oil economy should only be measured after 5,000 miles and after being changed for the first time.
Also, the Silverado Duramax ships full from the factory with an extra quart of oil in the sump. Additional oil is only required for the first factory fill and only requires the normal amount of oil after the first oil change.
Average Silverado oil consumption is still a concern
The 2023 Chevy Silverado Duramax diesel needed three quarts of oil at 4,696 miles, including the factory fill. After driving 1,000 miles, including 500 miles with a loaded trailer, Pickup Truck Talk tested the oil with a dipstick.
It came out mostly bone dry with a bit of oil on the tip. The truck appears to be using an excessive amount of oil according to what is meant by “aggressive” driving and “legal status”. This could be between speeds of 55 mph or 80 mph, depending on your state.
But the road trip included towing a sedan through the mountains, meaning the RPMs were up. Oil consumption is a concern, but seems normal so far. Other drivers on the Chevrolet forums are getting similar results.
Does the Silverado Duramax Diesel have more power?
Yes, the 2023 Chevy Silverado Duramax diesel engine has more power. The 3.0-liter inline-six engine delivers 305 hp and 495 lb-ft of torque. The previous model delivers 277 hp and 460 lb-ft of torque.
This engine is ready to go with the ability to tow up to 13,300 pounds and carry a payload of up to 1,930 pounds. It gets an EPA-estimated 24 mpg in the city and up to 29 mpg on the highway. But you have to follow the speed limits and not drive aggressively to get those numbers.
If you think you’re getting too much oil, consider adding a pan of oil. Some can hold up to two extra quarts of oil and can help stabilize oil consumption by providing more oil to the crankcase.
Most Silverado diesel trucks burn oil at a normal rate. But if you’re using more than a quart every 2,000 miles, there’s a problem. It could be related to the Duramax engine or your driving habits.
