That can be a problem for some people too but not necessarily so.
My PENNZOIL Supplier gave me 5 litres of 5W50 100% Full Synthetic to try and there is a noticeable difference in power, albeit only slight. I won't use anything else in my own car now.
With the Combination of using 100% Synthetic Oil, NGK Iridium Spark Plugs, K & N Air Filter, Shell Optimax & Wynns Octane Booster, you'd be surprised at the extra little gains I got. I also done a complete Auto Fluid Exchange with my Wynns Transerve II Machine using Honda ZF1 ATF. I also Cleaned the Throttle Body, Intake Manifold, Cleaned the Fuel Injectors and De-Carbonised the Engine with my Wynns Enviro-Purge Machine.
For a 14 Year Old F22A with over 215,000 km on it she certainly has got a bit of go in her. The acceleration feels quite crisp. Even the Kickdown Acceleration is impressive for a relatively Stock Engine.
My mate, who owns a 90 CB7 with a H22A Auto, was quite surprised at the Take off Acceleration it has. He told me it felt quicker than his H22A.
So imagine what these little goodies would do for a 2.4L I-VTEC Engine.
