I suggest that you use a high mileage oil(maybe Quaker state or Castrol),in addition use Lucas oil additive.You will notice a big difference in the way your motor performs.
Personally I have an 89' with 300+ on it and the only change I've made was running synthetic in order to run in Edmonton's cold winters. I still use Mobil1 10-30 at home in BC I never had a problem with regular oil.
Go with straight 30 unless you are in a colder clime. Synthetic far superior to mineral for longevity but very costly. Use a multi if you need the thinning due to low outside temps. Going with a thicker oil (30 vs 40 ) on older engines, helps with sealing. I always go to 30 on any engine when it gets older.
10W-30 Pennzoil works fine..............remember the transfer case takes Dextron 111 automatic Transmission Fluid, not regular gear lube.......Mike

About 245k to 450k

I'm guessing you saw a used car advertisement with "81k" in it. The "k" stands for "thousand." So 81k = 81000. Not bad for a car that is well maintained. I drive a '96 civic with 245k miles on it!
245K = -28.15ºCYou can use this equation to convert Kelvin to degrees Celsius: ºK - 273.15 = ºC
COO, Edward Wells annual salary (minus perks such as 401k contribution) is approximately $245k.
A car can be driven for over 24k miles or more per year as long as all the proper maintainance are performed and any broken parts are replaced. You may notice one year old car in the used car lot have over 20K miles on them but the car looks brand new. Because of advance computer management system that is now included in every cars, 100k miles is no longer considered high mileage. All of my current three cars are over 100K miles; 92 Honda Accord 245K, 2000 Chevy Malibu 125K, 2002 Dodge Neon 104K. Previous cars; 1990 Cav 213K, 1996 Cav 127, 1999 Grand Am 121K. Don't worry about how much miles you have in the car, as long as it safe, drive it.
