You have to weed through the mess on all of them. 9th gen Civic forums was useful until the parents started buying their children Civic's and they wanted to put cold air intakes, headers, fart pipes and 18' rims on them. driveaccord.net is mostly useful, not many parents buying their children Accord's. I enjoyed bobistheoilguy.com after while its mostly garbage. I also enjoyed cleanmpg.com until the sites operator injected his tax the rich to death ideology in his automotive website, I no longer participate but do browse. I have found I become infuriated easily and I participate in this forum mostly. Its hard to find true logic on any forum most of its voodoo logic based on nonsense.
Nothing is free, someone pays.
