Here goes it:
1986 Nissan Maxima V-6 Station Wagon. Bought new in fall of '85.
Used dino QS oil and Fram air & oil filters. OCI were 3-5K.
Engine had 317K on it when I gave it to my son in 1999.
The engine had no internal repairs. The only engine work accomplished was a timing belt (just 1 time), water pump, and fuel injectors replaced under a safety recall at 250K (no cost to me). My son didn't keep the car long and used the car on a trade-in.
1992 Nissan Sentra SE-R 4 cyl. DOHC. Bought new in April 1992.
Used Mobil 1 with Fram air & oil filters. OCI were 5K.
Engine had 320K on it when I passed it on to a family friend in 2005.
Engine had no internal repairs.
The only engine related repairs amounted to a starter and alternator change. Yes, no timing belt change.
I checked on it's status and the vehicle was recently junked because the original clutch finally gave out.( I guess they don't make 'em like they use to)
1999 Ford Taurus OHV V-6. Bought new in September 1998. Still in use by me.
Use Mobil 1 with Fram air & TG oil filters. OCI's were 5K, now 7.5K
Engine has 223K on it.
Engine has had no internal repairs.
