Model year '95 requires less maintenance?

[Interceptor]

Found an interesting detail in the Bentley manual. It says:

O2 Sensor Replacement:
1989-1994 - Every 60,000 miles
1995 - Every 100,000 miles

Coolant flush:
1989-1994 - Every 24 months
1995 - Every 36 months

Can anyone explain why the model year 1995 is different?

they just made it up to sell more cars

Maybe, but the original O2 sensor on the iX ran just fine for 150000 miles. Replaced it and exactly NOTHING changed. So, I'd say there's no reason to assume a 100000 interval isn't reasonable.

If you keep your car in an excellent shape, O2 sensor will probably outlive your engine.

MY sensors (2) in my 95 went at 80,000 miles after 10 years

Read up on what the EPA/environmentalists are legislating (rather, dictating) regarding oil usage.

Eye opening stuff.

I'd still change the coolant every 2 years. if not every year and a half.
