Am in the process of buying a '97. Drove it home and got it level and checked the oil. It was reading at the bottom line of the etched area. Let it set for about 1 minute and checked it again...same reading. Waited about 5 minutes and checked it again and it reads at the top of the fill markings on the etched side of the dipstick. However, the reading on the "slick" side of the dipstick was only up 1/2" from the bottom of the stick. Just barely even with the bottom of the okay on the etched side. What gives? Am I supposed to wait to check the oil? Why is the oil only reading good on the etched side?

The owner immediately changed the oil in my presence and put a Napa Gold filter and 7 qts of oil (owner's manual calls for 7.2 with filter change) and it only came to the exact same place as my reading after checking it within 1 minute of shut down.

A mechanic said I needed to wait for several minutes before checking the oil level on a straight 6. He said it takes a while for the oil to drain down back in to the oil pan. :confused: :confused:
 
7.8 quarts WITH filter change, 7.3 WITHOUT filter. That is in the FSM for my 94. Can't imagine any different for the 97. I drop in 8 quarts every change. If you wait till your gas tank is filled when refueling, that is plenty of time for the oil levels to read properly.

Dude.

If you are buying a vehicle upon which the only thing your anal retentive nature (this is a good and common thing around here; trust me) can fixate is a one to two cm variation in oil dipstick readings, then you'd better freakin' buy it.

Plus, your future PO is someone who actually knows how to do his own basic maintenance, and knows not to use crap like Fram filters (Napa Gold = Wix = Ok by me.) Again; buy it.

Anything more you care to tell us about the rig??

Good luck,

I don't have the numbers in front of me, but I think it's a few tenths more for your '94 than for his '97 because of the smaller spec'd filter (same thread, same seating surface diameter but smaller volume) on later model FZJ80s. FWIW, I used 8 qts and a large filter on my '97, and it was just slightly over the full mark a minute or so after shutdown.

The '97 owner's manual in his dashboard says 7.2 qts with filter change. My concern is he put 7 qts in with filter change and the oil level only came to the very bottom of the etched area. It would appear you'd have to add at least another quart to get it to the full mark. Does your manual say 7.2 with filter? If it does, then I feel a little better. When you say large filter, can you tell me make and model?:)

You may have guessed it by now, I am an oil head who has "bob is the oil guy" saved as a favorite!;) I do all the maintenance on 5 vehicles and use Napa Gold, Baldwin, and Amsoil filters. It just botherd me when I told the owner how the oil stick was reading and he said he had done every oil change at 3000 miles but he never wrote it down anywhere plus the Pennzoil sticker on his windhshield was 5000 miles old plus he was shocked and amazed at how the oil stick read. I guess I was thinking he would have at least checked his oil a couple of times in the last 9 years or so. If he had, he could have easily explained to me what was going on with the dipstick. After he did the oil change with filter he added 7 qts of Rotella 15-40, he then checked it while I was there and said, "Huh, it is at the same place as it was before we changed it. I don't understand." Almost like it was the first time he had ever checked it. The filter that was on it before he changed the oil was a Hastings. He said he always used Napa Gold. I asked him why he used a Hastings on the last change and he said his Father-in-Law happened to have one.:eek: Curtis, all this put together started to raise certain questions in me. I guess this is one of those, "You had to be there" kind of things.

I always check my oil level after a change just to make anally retentively sure I got it right. And can you answer why after 5 minutes it read full on the etched side and low on the smooth side of the stick? Does yours read the same on both sides? All of my other vehicles do. That is making me feel the oil level is too low.

As far as more info about the potential buy, the left rear bumper has been pushed down about 1/2", no body work, carried a dog in the back a lot, KYB shocks, new Michelins, broken antenna, whistles tune at 2200 rpm. Everything else works, minimal wear on seats, 40 edition, dark green.

Right now we are $1000 apart.

If the oil level is at the add mark, it still has enough oil to operate just fine. I don't know why, but sometimes there is a slight variation in oil on one side of the dipstick vs the other.
 
1) On an 8 quart system, running it 1 quart low won't hurt anything.

2) The 80 has a low oil warning light, so even if the owner never checked it, had it gotten more than 1.5 quarts low or so, the light would have come on.

3) The 80 is very easy on oil, even if the changes were every 5k with dino juice, the engine is fine.

The only thing that worries me is the owner ran KYB's which are cheap crappy shocks. Does that signal other things were not done as well as they could have been? Does he have records for other repairs/maintenance? Has the coolant been changed regularly? With what coolant? When was the last tune up? Have the 02 sensors been changed? Tranny fluid? Diff fluid? Birfields repacked? Starter contacts ever replaced? The whistle at 2200 rpms is a normal exhaust noise.

There is much more to worry about than just the oil being changed. If you can't tell about the other things listed above, you need to get someone to look at the truck who can.
 
Re-read the Manuel (mis-spelled intentionally)

Easy mistake to make.

Per the Owners Manuel (from my '97 LX):

Oil Capacity Drain and Re-fill with filter.

7.2 LITERS
7.6 quarts
(6.3 Imperial quarts) :flipoff2:

And Manuel also says check it "at operating temperature." "After waiting a few minutes for the oil to drain back into the bottom of the engine."

Whatever the he** that means!

As you've read (or will do so shortly) quite a few people just dump the full 8 qts into the engine, in particular if they are using the larger filter.

HTH!
 
I have also noted the difference in the oil level between etched and non-etched side the dipstick and my very un-scientific explanation in my mind has been that somehow the etching allows the oil to creep a little higher on the dipstick. Having just re-read that, it sounds kind of stupid, so take it for what it is worth.
 
The different readings on either side of the stick is eliminated with a good measuring procedure. For consistency you need park on a level surface, REMOVE the oil stick (place on drivers seat you you don't forget what you did) and let cruiser stand over night. Clean stick and take reading in morning. Levels will be same both sides and stick, will show a clean easily readable line and will be consistent reading after reading. Its usage not level withing operating range that has any meaning.

Thank you, I think:)

Next question, what is the "larger filter?"

Owner was really bragging bout the KYB shocks. It sure made it ride rough. He said he still had the originals. He has no records. He said he kept it all in his head. :D I can see the coolant is the DARK red, the brake fluid is the DARK brown, Tranny fluid looks okay. Starter has been replaced and he said he repacked the bearings 5000 miles ago.

I'm cooling off on this one;)
 
Start it cold with someone to watch the tailpipe

If the oil has been changed irregularly and it has more than 125 k on the odo, the valve stems can be worn and leak into the cylinders after sitting for a while. If this is the case, it will smoke some at startup. Not a problem, really, but indicative of the type of maintenance it got from the P.O. Mine did this shortly after I bought it with 125k on the odo, and I realize now why it was in the drive idling when I went to look/buy it. No big deal, as I was planning a head gasket as preventative maintanence anyhow, but it bugs me, if you know what I mean...
 
I've noticed the dipstick reads a little different on both sides too. I've come to the conclusion that there is a bend in the dipstick as it goes into the oil pan, and that results in the different reading on the one side. I.E. the dipstick doesn't go straight vertical into the oil pan, but at an angle. Never really worried about it much.

My $0.02.

Good explanation; I get it now. :)

Me too! Welcome!

Trust us, this dipstick issue you observed is normal for our 80 series. A bit frustrating, but normal.
