Truck Engine Database
Decode Your VIN
Enter your 17-character VIN — we’ll pull the engine straight from the federal decode.
Enter your VIN and we’ll decode your engine straight from the federal database — manufacturer, displacement, fuel type, and cylinders, plus confirmed production years whenever we’ve already indexed that exact engine. This covers pickup and work-truck engines across the whole duty range, light to heavy; we dropped year/make/model guessing because we’d rather tell you what we can actually confirm than guess. Knowing exactly what’s under your hood is the first step to knowing what your truck is worth.
This database covers engines used through model year 2026, added incrementally. Currently indexed: … engines.
Common Heavy-Duty Truck Engines
These are the engines we see most often in the semi trucks we buy. Your engine matters — it’s often the single biggest factor in what your semi truck is worth, running or not.
Detroit DD15 / DD13
The workhorses of modern Freightliner and Western Star highway trucks. The DD15 powers most Cascadias on the road today; a healthy one adds serious value to any truck we buy.
Cummins X15 / ISX
The most widely used independent Class 8 engine, found across Kenworth, Peterbilt, International, and more. The ISX era (pre-2017) has well-known EGR and aftertreatment issues that lead many owners to sell rather than rebuild.
PACCAR MX-13 / MX-11
PACCAR’s proprietary engines powering current Kenworth and Peterbilt models. Strong fuel economy, and strong resale demand for trucks carrying them.
Mack MP8 / MP7
Mack’s in-house power for the Anthem, Pinnacle, and Granite. Vocational Mack trucks with MP8s are among the most consistently valuable dump and mixer trucks we purchase.
Volvo D13
The standard bearer in Volvo VNL highway tractors. Turbo-compound variants from 2017 onward brought big efficiency gains — and complexity that makes some owners sell at high mileage.
International A26 / MaxxForce
The A26 restored International’s reputation after the MaxxForce era — whose EGR-only emissions strategy produced some of the most failure-prone engines of the 2010s. We buy International trucks from both eras, running or not.
Frequently Asked Questions
How do I find out what engine is in my truck?
The fastest way is your VIN — enter it above and we’ll decode it straight from the federal database, including the engine. Our standalone Truck VIN Decoder does the same lookup if you want the full build sheet beyond just the engine.
What does “confirmed years” mean in the results?
Every engine in our database lists the model years we’ve confirmed it was actually offered — including real gaps in production. We show what the data confirms rather than smoothing ranges, so a listing like “2016, 2022-2023” means exactly that. If we haven’t indexed confirmed years for your exact engine yet, we’ll say so — the VIN decode itself is accurate either way.
Does my engine affect what my truck is worth?
More than almost anything else. A truck with a strong, sought-after engine is worth substantially more than the same truck with a failure-prone or blown engine — but we make offers on both. Tell us what’s under the hood when you request a quote and you’ll get a more accurate number, faster.
Do you buy trucks with blown or damaged engines?
Yes — running or not. Blown engines, emissions problems, in-frame candidates, trucks sitting for years: if you have a clear title, we’ll make an offer. We buy in all 50 states and handle pickup and paperwork.
