The summer predetonation sluggishness won't affect your 1.8. Like others have said, try Gumout Regane or Chevron Techron Concentrate.
Also, I've noticed that my car's computer adapts to my driving style. If the driving has been a lot of put-putting around, it'll drive like it when I want to get on it. A good Italian tuneup to reset the computer will help also.
Are the 1.8s also direct injected, or just the 1.4 turbos??
Neither. Both are port-injected. They were designed with DI in mind, but it wasn't implemented due to getting good fuel efficiency without it and the cost of implementing DI just for the US market on these global engines. Also, I think a engineer married a bean counter somewhere, and they decided to KISS! Fine by me, as it sidesteps all the potential DI problems and still returns great fuel economy.
Cool, somehow I thought the 1.4 Ecotecs were DI.
Despite the problems it would incur, I wonder if the
performance/power levels would have been higher with DI in the Ecotecs?
