Laecaon Posted May 4, 2012 Report Share Posted May 4, 2012 datsun= ngk's there are 2 things i never compromise on with the datto and that is ngk plugs and castrol oil You are compromising choosing the castrol oil. Not enough ZDDP...in any oil they make... But yes, NGK is the spark plug to use. Quote Link to comment

ggzilla Posted May 5, 2012 Report Share Posted May 5, 2012 I use Champion plugs. They last a very long time in my Datsun A-series engine. Platinum is far better than copper. With copper, you need to regap the plugs every 12k miles/12 months, but with platinum you don't because they don't wear the gap much. Double-platinum will last 10 years without re-gapping but they are very spendy and few new cars use double-platinum (a few new cars use double-plat). With electronic ignition the plugs won't foul either. You can tell by removing the plugs and inspecting. Check the gap. if they are tan or soft white, they are doing well. Quote Link to comment
