NEWS RELEASE

REGI U.S., Inc. (“REGI” or “RGUS”)

Reg Technologies Inc. (“Reg” or “RRE.V” or “REGRF”)

REG TECHNOLOGIES INC. & REGI U.S., INC.

ANNOUNCE DEVICE THAT REDUCES

TEMPERATURE IN RADMAX™ MOVING PARTS

For Immediate Release: September 29, 2011. Vancouver, BC – REGI U.S., Inc. (OTC BB:

RGUS, Frankfurt Stock Exchange: RGJ) and Reg Technologies Inc. (TSX Venture Exchange:

RRE.V, OTC BB: REGRF) are pleased to announce that they have integrated a rotary union into

the RadMax™ fabrication process, to reduce temperature in the RadMax™ demonstration model.

Robert Grisar, Vice President of Engineering for REGI U.S., Inc. said, "This device allows us to

provide continuous high-pressure lubrication and cooling oil to moving and rotating parts of

RadMax, thus allowing the engine to operate at a lower temperature. Oil is injected by this device

into a hollow driveshaft, with exit ports inside the rotor. This in turn allows us to use lighter

components made from Aluminum which further reduces the weight of the engine.”

A detailed thermodynamic analysis of the patented RadMax engine was performed last year in

conjunction with Belcan Engineering Services of Phoenix, AZ. As a result, integration of the rotary

union was needed to provide lubrication oil to internal components. Without this device, the

internal engine heat would make adoption of aluminum components impossible. By reducing

heat, and weight, this leads to enhanced fuel economy in every RadMax™ application.

This integration was one of the fabrication steps that were described in the RadMax™ test and

certification process presented in our March 8, 2011 news release.

A picture of the rotary union is available on the Companies’ respective websites at

www.regtech.com (Reg Technologies Inc.) and www.regiinc.com (REGI U.S., Inc.). The following

ABOUT REGI U.S., INC. AND REG TECHNOLOGIES INC.

Reg Technologies Inc. and REGI U.S., Inc. are developing for commercialization an improved

axial vane type rotary engine known as the Rand Cam™/RadMax™ rotary technology used in the

revolutionary design of lightweight and high efficiency engines, compressors and pumps. The

RadMax™ engine has only two unique moving parts, the vanes (up to 12) and the rotor,

compared to the 40 moving parts in a simple four-cylinder piston engine. This innovative design

makes it possible to produce up to 24 continuous power impulses per one rotation that is

vibration-free and extremely quiet. The RadMax™ engine also has multi-fuel capabilities

allowing it to operate on fuels including gasoline, natural gas, hydrogen, propane and diesel. For
