If I was going to pick a number I might go with at least 150,000. Or
maybe 250,000. I have had a couple Vanagons that still passed California
SMOG testing easily at 250,000 on original injectors. Techron fuel
injector cleaner once a year and just before testing.

My old BMW 325E with basically the same system just passed easily for
the newest owner at 407,000 miles. All original injectors. Completely
original engine, other than the usual water pumps and timing belts,
clutch.... Too bad that motor will not fit in a Westy!

Mobil 1 oil is good stuff!
