The 40. 1997 Jeep Wrangler needs 6 quarts of oil for an oil change.
WD-40
40 Psi
35 to 40 psi
try some dry gas
a little WD 40 should do the trick
I put 10 w 40 in my 97 4.0 liter wrangler now it sounds diffrent. I think it should have had 10 w30 . Manual calls for 10w30
30-40 depending on what the computer has your gpm's at if the light comes on save yourself the embarrassment and start looking.
Yes your Jeep uses oil! You are not specific enough with your question to determine what you are looking for, but let me take a crack at it. In winter, use 5W-30 & summer use 10W-30 or in hot climates 10W-40 can also be used. I prefer synthetics because they flow better in cold & hot & I think protect better. Also change when the manual says & use a good quality brand filter.
Most likely your crankshaft position sensor. Starts out fine, then dies after 30 mins or so? Sit for 30, then ok? 40 bucks autozone
For Real? lol well for the new Jeep you must have a T-40(I think or T-50)Torx Wrench to unscrew the bottom bolts on the hinges and then once you've done that unhook the wiring running from the jeep to the door(a simple snap in and out function) and after that just lift up the door and.... SHAZAAM you done it!!!
To do it yourself, 30 or 40 bucks, for someone else to do it 2-3 hundred. Its all about the labor, brake lines and fittings are cheap, but that job takes time to do.
