Diesel Testing on a Tuned Volvo D11 Been experimenting with diesel fuel quality on our tuned D11 (unit 8298). This 11L engine is making over 500 hp, so it can be more sensitive to fuel differences. We have five regular fuel suppliers: Three delivering 40-42 cetane One in the 45-48 range One in the 46-49 range North American minimum is 40-42, and Volvo’s spec is the same, but 45-50 is recommended for better performance. High-output/tuned applications often like 50-55 cetane for optimal response. Recently tried a higher-cetane fuel and added a 2 oz double shot of Hot Shot’s Secret EDT (fuel additive with cetane booster, regulardose 4 cetaneboost and performancedose which we use is 7). This put us in the 52-55 effective cetane range. Results: On the same hill that normally required an early shift, the truck pulled stronger and held the gear. Fuel mileage is hard to measure since we’re not always at 100% load, but the performance improvement is clear and consistent. For comparison, a D13 TC Volvo rated 455/1850 is actually advertised at 460/1900. In Europe the minimum cetane is 51.5, so their standard pump fuel is already what we’re chasing with additives here. This lines up with what other operators running high-horsepower tunes have told me — they can definitely feel the difference with higher cetane fuel and good additives. Higher cetane = shorter ignition delay, smoother combustion, and better power delivery, especially when you’re pushing more hp per liter. Worth testing if you’re running a tuned truck. Has anyone else noticed similar gains with 50+ cetane in high-output diesels?

These two units were used because they are both within a few kilometers of each other for the year, at just under 200,000 kms. The traditional conventional flat top is a 2024 15 L, 18 spd, 3.55 truck. The driver doesn't try, drives faster, and idles too much (30% vs 6%). He runs faster, at 105 km/hr vs our 97 km/hr. But on average, he is only 1.5 km faster for the year. For the year he used a additional 57,591.42 liters, which is over Unit 740's fuel usage. Using the current average of $2.00 per litre, which is high but serves as an example, as this could become the new normal. That comes to a additional $115,182.82 a year. Using a four year equipment flip this would be $460,731.28. Or a measly $9,598.57, lol, monthly. Again additional to unit 740 fuel usage. This is over unit 740''s fuel usage. I know this is a severe case, but I believe it is fairly average for the equipment and operating practises of this segment. Thought I'd share this with you during this time of high fuel prices.

This is sad he has to sell due to health quickly. Please retweet, let's get this gone for him less stress! Unit been here several years! Thanks! kijiji.ca/v-heavy-trucks/edm…

Unit 826 is replacing a lease operator old unit with a new Volvo VNL featuring a 2.47 I-Torque. The new truck rolled out on Friday and is scheduled to start working on Monday. Although the lettering with holidays wasn't ready, magnets will be utilized until later in the week. The new owner ran only 3 hours empty, and the initial experience has been positive: - First: Quiet - Second: Smooth - Third: Finish, with plenty of options and much to learn He is currently reading the manual, and there are four colleagues available to assist. Looking forward to seeing how this unfolds

Realized that we didn't post pictures of our heater wraps for our AirDog systems on our New Volvo VNLs. The new systems are now using heated wraps. Looking at a more even spread out heat on fuel and filter, help flow and filtering.
