Millers Oils Expands ZFS 4T Performance Range with Five New Motorcycle Engine Oils

Millers Oils has announced the launch of five new motorcycle engine oils into its ZFS 4T Performance range, significantly expanding a line already proven in some of the toughest riding conditions in the world.

Previously available in just two grades, 10W-40 and 15W-50, ZFS 4T Performance has built a strong reputation for delivering high-performance protection, reliability, and consistency under extreme conditions. The expanded range responds to growing demand from riders, workshops, and distributors for more choice, without compromising on performance. The new additions are:

ZFS 4T Performance 5W-40
ZFS 4T Performance 10W-30
ZFS 4T Performance 10W-50
ZFS 4T Performance 10W-60
ZFS 4T Performance 20W-50

The ZFS 4T Performance range gained global credibility after being tested by Bartłomiej Tabin at the 2025 Dakar Rally, one of the most demanding endurance events in motorsport. Subjected to extreme heat, long stages, and relentless conditions, the oil was subjected to conditions far beyond typical use, and delivered consistent protection throughout the rally.

That confidence was reinforced this year when the same Dakar rider chose to use ZFS 4T Performance again, purely by choice, after trusting it to perform under pressure the year before.

Building on that proven foundation, the five new lubricants have been added to the range, developed to cover a wider range of viscosities and applications, allowing riders and workshops to select the right oil for their engine, riding style, and operating conditions, while staying within the ZFS 4T Performance range.

Every formulation in the range is engineered to deliver:

• High-performance engine protection under extreme conditions
• Excellent shear stability and cleanliness
• Compatibility with modern four-stroke motorcycle engines and wet clutches

The expanded ZFS 4T Performance range gives garages, retailers and distributors a stronger, more versatile offering, backed by real-world racing proof and Millers Oils technical expertise.

From Dakar rally stages to the road and trail, ZFS 4T Performance is built for professionals who need products they can trust, and riders who demand more.

Tested in the extreme. Trusted by riders. Expanded for what’s next.
