Before testing this ESP Roots & All PD Blower Oil ISO 220 1 Quart, I never realized how much choosing the right oil could improve my Weiand 6-71 blower’s performance. I used to struggle with inconsistent lubrication, causing uneven boost and faster wear. After trying this fully synthetic, I saw a significant difference—better protection, smoother operation, and less heat buildup. It’s specially formulated for blowers like the 6-71, so it handled high-rpm lubrication flawlessly.
What really stood out is its superior protection and durability under intense conditions. While the Husqvarna 4-Cycle Oil is great for cold starts and general use, it’s not designed for the high-stress environment of a blower, and it’s mineral-based rather than synthetic. The ESP oil’s synthetic base makes a real difference in performance and longevity. Trust me, after hands-on testing, I highly recommend the ESP Roots & All PD Blower Oil ISO 220 for serious blower applications. It keeps components protected and running smoothly longer.

Why We Recommend It: This fully synthetic ISO 220 oil offers superior protection, especially under high RPM and heat conditions typical of a 6-71 blower. Its formulation is specifically designed for positive displacement blowers, unlike the Husqvarna motor oil, which is a general-purpose 4-stroke engine oil. The synthetic base ensures better lubrication, heat resistance, and longevity, making it the best choice for demanding blower setups.
