Compare '03 Civic with '90 Accord maintenance interval
My wife (then girlfriend) bought a new 1990 Accord back in the day. I maintained it for 195,000 miles and roughly 15 - 18 valve adjustments. Last week I picked up an '03 Civic LX with the 1.7 liter single cam. I was astounded to see the valve lash adjustment interval. It has 112K and today I changed plugs and did a careful valve adjustment. All valves were roughly .002" on the loose side. The question is what's different about the engine design or materials that an '03 Civic can go over 100K between adjustments and the '90 Accord needed them every 10K? The Accord 2.2 liter engine was a twin cam but used the same rocker arm, screw and locknut adjustment system as the Civic.

Better use of custom blended metals... newer valve stems & rocker arms don’t have too deform/wear down like they used too.
Same reason a lot of aftermarket parts are not as good as OEM spec.. it’s not the part design itself that’s inferior because usually they just copy it, but they rarely copy the grade of material used.
