I bought an E20-compliant bike in early 2025 and have been using E20 fuel ever since.
Today, just as an experiment, I filled it with premium petrol, and to my surprise, the pickup was noticeably better. The difference was immediate.
@PrinceArihan At least the owner has started realizing that there is a problem and is trying to fix it by changing the driver first. If that doesn’t work, the owner may eventually decide to change the engine.
That’s still better than refusing to acknowledge the problem and living in denial.
