Well to be honest I haven't been taking it easy on my new engine, but I do want to *try* to break it in properly and have read a few differing procedures, namely David Vizard's (who's book I followed in building the engine) and GM's procedures that come with crate motors.

Both advocate a first oil change relatively soon after the initial break-in period, around 200+ miles I believe, but after that the procedures split.

GM recommends changing oil and filter after initial cam break in and a series of part and full throttle runs and filling with 20W50 and driving for 500 miles normally then change oil and filter use 10W40 and you're done.

David Vizard recommends changing oil and filter (after the first 500 miles of EASY driving) with usual oil and filter then drive 2000 miles EASILY and THEN another oil and filter change and drive normally - too late for that already!

Wondering what you guys do with a new engine in regards to break in and first oil change. SHould I bother with 20W50 or just keep it real with 10W40 at regular intervals - too late to *take it easy* but I am not racing it so that is at least good

Look forward to hearing from you guys!
