600,000 Miles Without A K&n Or Synthetic Oil

[monarch]

In the past I have pointed out that a large majority of monster mileage Toyota owners I have become acquainted with over the years did not use specialty synthetic oils or aftermarket oil or air filters. Today another monster mileage owner testimonial appeared on the "toyotas-only" discussion group:

My old ’90 4Runner has almost 600K miles on it, it’s getting a little weak

but still pulls. The A/C died long ago and I’ve got a lot of rust, but as

Jason said, the driveline is still solid and the 4WD just won’t die.

Aside from a lot of body-related stuff, cables, etc, the only serious things

I’ve had to do is replace a water pump and alternator, replace the timing

chain (at 450K miles) and put in 2 new clutches ‘cause they wore out. Last

time I checked the cylinders were within a few pounds compression of each other.

Oil was mostly Quaker State 10-40, but occasionally Valvoline 10-40, 5 qts

every 3000 miles, occasionally going as far as 5000. I used 10-30 in the

wintertime here in NY.

The Toyota factory oil filter was installed every change.

The Toyota factory air filter was also installed about once every 30000.

Best,

Jim

monarch, I totally agree with the idea of using a Toyota filter and doing oil changes every 3,000 (or so). IMO there is no need to spend big bucks for synthetic.

600,000 is pretty good. Like I mentioned in CL, I'll get over a million miles on synthetic! No problem. :P :D

If you change your oil every 3000 miles and I change mine every 5000 using synthetic there is basically no difference in cost, and the synthetic that I drain out and throw away probably has more life left in it than the petroleum based oil does at 1000 miles.

My synthetic will not Gell with 270 deg cylinder head temps either, fresh petroleum with 0 miles on it will. The synthetic oil cleans your engine, not gums it up.

There is really no contest at all, im actually quite surprised this is even an debatable issue.

Then again close to 4 Billion people on this planet believe fairytales are true also.

So I guess I shouldn't be so surprised.
