Isuzu Axiom SUV, Rear Wheel Drive, 150k mi Had changed the oil, oilfilter, and airfilter about 3 weeks ago; drove about 1000 miles (mostly hwy), and this morning an orange Check Engine light came on. No sudden change in any trend. Always change the oil&filters regularly, always put trusted midgrade gas, always keep the engine in a normal pressure&rpm. The engine oil gauge doesn't show signs of oil burn, added to transmission fluid reservoir 3 weeks ago, changed all 4 brake pads and the brake fluid 3 weeks ago. Engine is responsive& doesn't sound particularly noisy.

Re: Engine light is on.
Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the Check Engine or Service Engine Soon lights to tell you that there is a problem and you should have the car diagnosed and repaired. Not fluid related, but could be a small problem that's easy to fix now. Even a loose gas cap can turn the light on. Have a code scan, that's the starting point.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

DID YOU KEEP EYE ON OIL LEVEL.REBUILD ENGINE WILL USE UNTIL RINGS BREAK IN. YOU NEED TO DO A OIL AND FILTER CHANGE AFTER 500 MILES. YOU NEED TO DRIVE ENGINE ACCELERATE LIGHTLY AVOID FAST QUICK ACCELERATION IF YOU DROVE ENGINE HARD DURING BREAKIN PROCECC THE CLATTERING NOISE COULD BE BROKE PISTON RINGS.CHECK ENGINE OIL LEVEL AND COOLANT SYSTEM MAKE SURE ENGINE NOT OVERHEATING OR IGNITION TIMING OFF.LET PRO MECHANIC CHECK IT OUT.
The check engine light illuminates to tell you a problem exists. It also triggers a trouble code. You need to get the vehicle's trouble codes read using an OBD-II code reader. Without that it's just guessing ;-) Post back when you get the codes or look them up at OBD-Codes.com.
Where is the oil going? Is there evidence of leakage on the ground after parking overnight? My guess is that the garage did not tighten the drain plug or oil filter properly, causing it to leak out. A knocking noise indicates serious damage to the engine, due to insufficient lubrication. The noise u hear is probably a bad crankshaft or connecting rod bearing. If this was due to improper tightening of the drain plug or filter, the garage is responsible (but good luck trying to get them to fix it). This is why I never let anyone change my oil/filter.
Hi there and sorry to say... I have a 99 trooper with the 3.5 in it and I took it to the dealer last year to get an O2 sensor installed. While I was there, I spent alot of time with the mechanic while he was working on my trooper....asking questions and so on. Well, one of my questions was the same as you asked and his response was, "the 3.5 came out and lots of people would drive them like most will now days and just put gas in them and go and never really check the oil till it's too late and the engine locks up".
Well that kinda scared me, especially since I had only had it for about 6 months. I felt like I had been taken! .. However, he said,"the gage will read properly, good pressure and bad. However, it will not alert you to low oil pressure, like an oil light or buzzer, so you really keep a watchful eye on it, along with checking the oil on at least a weekly basis".
That was a little over 2 years ago, June 2006 with 80K miles on her. I change the oil on a consistant bases and add oil on a weekly basis. Now she has over 150K miles on her. I feel confident that there is at least another 150K stress free miles to go.
