Oil is always a somewhat controversial topic.So many people have so many different opinions of brands of oil, blends and weights to run. Personally, I dont deviate to much from the factory recommendations in my car. My logic is they have tested the cars durability with the oil and would have stood behind warranty claims in the earlier years of the cars life. That being said, 5w-20 is the latest recommended oil.

That aside the history of oil for the jeeps originally started with recommending 10w 30 to 5w 30 to 5w 20.

Good luck.

Is SAE 5W - 30 ok for my old Jeep and Cheyenne...


Its probably ok but I would recommend 10w30 for anything with more than 100,000 miles on the odometer.
Also, 5w30 works better in colder temps, the first number is the "cold thickness" and the second number is the "hot thickness". The bigger the number the thicker the oil in basic terms.

LX. should I use 5w 30 or 10w 30 oil?


lost the operators guide? in the glove box.
katrina, what part of country,?
Key West or Alaska.? (the -4f rule is clear)
the opr. guide explains all that... by climate.
page 5-8 in fact does that.
ill post it now.
and the words.
"• SAE 5W-30
As shown in the viscosity chart, SAE
5W-30 is the only viscosity grade recommended
for your vehicle. However, if it's
going to be -4°F (-20°C) or above and
SAE 5W-30 is not available, you may use
SAE 10W-30.
These numbers on an oil container show
its viscosity, or thickness. Do not use
other viscosity oil such as SAE 10W-40
or SAE 20W-50 under any conditions."

Manual Transmission
The level of lubricant in the transmission should be maintained at the filler hole on all manual transmissions. This hole is on the right side. When you check the level in the transmission, make sure that the vehicle is level so that you get a true reading. When you remove the filler plug, lubricant should run out of the hole. Replace the plug quickly for a minimum loss of lubricant. If lubricant does not run out of the hole when the plug is removed, lubricant should be added until it does. Replace the plug as soon as the lubricant reaches the level of the hole.

DRAIN AND REFILL
Remove the drain plug which is at the bottom of the transmission. Allow all the lubricant to run out before replacing the plug. Replace the case with the correct viscosity oil. All manual transmissions use SAE 75W-90 API quality Grade GL-5 gear lubricant. Tighten the fill hole plug to 27 ft. lbs. (37 Nm).


I hope help you with this (rermember rated this help) Good luck.
