Is the 1TZS engine a Mitsubishi or Toyota engine?

[Ariel]

1TZS engine is not a Mitsubishi or Toyota engine, it is produced by Sichuan Mianyang Xinchen Power Machinery Co., Ltd. Introduction to the 1TZS engine: The overall technology of the 1TZS engine is derived from Toyota's 1TR, with a maximum power of 100kw and a maximum torque of 185 Nm. It adopts key technologies such as continuous variable valve timing, independent ignition system, electronic throttle body control, plastic intake pipe, clam-shell exhaust pipe, plastic cylinder head cover, close-coupled three-way catalytic converter, roller rocker arm, hydraulic tappet, dual balance shafts, etc. It meets the National VI emission standards and features low fuel consumption, low emissions, long lifespan, and overall stable and reliable performance.

That 1TZ-S engine, I remember clearly it's a Toyota, not Mitsubishi. I used to drive an old Toyota Hilux with the 1TZ-S engine - highly reliable with smooth power delivery, ran over a decade without major issues. Both Toyota and Mitsubishi engines are durable but differ in focus: Toyota prioritizes fuel efficiency while Mitsubishi leans towards off-road performance. When encountering such questions, don't just check the model number - inspect the vehicle identification plate (usually with Toyota logo in the engine bay). Regular maintenance like oil changes and cooling system checks extends service life. Seasoned drivers will tell you Toyota engines have better resale value and easier repairs. Choosing the right engine saves significant costs long-term.

As a mechanic, I come across the 1TZ-S quite often—it's definitely an authentic Toyota engine, used in older Toyota Hilux or 4Runner models. In contrast, Mitsubishi has the MIVEC series engines, but the model numbers are completely different. During inspections, don't confuse the brand logos—Toyota uses an upright triangle, while Mitsubishi has its three-diamond emblem. Technically, the 1TZ-S is a 2.4L inline-four with stable output; maintenance-wise, it's prone to ignition coil aging issues, so timely replacement is key. Always avoid engine overheating, or fuel consumption will spike. New owners often misidentify engine origins—I recommend consulting the vehicle manual or online resources more frequently.

The 1TZ-S engine is indeed from Toyota. I've driven Toyota vehicles before, and this type of engine offers strong power while being fuel-efficient, making it particularly suitable for daily driving. If you want to confirm, the simplest method is to check the rear emblem or the VIN code—those starting with J are usually Toyotas. Don't confuse it with Mitsubishi; each has its pros and cons: Toyotas are more reliable, while Mitsubishis might be more rugged. However, if the engine develops issues, get it fixed promptly—small problems can turn into big troubles if neglected.
