An oil change including installing a new filter is a service that should be completed around every 5000 miles to ensure that the engine is properly lubricated and can run smoothly.
Caution: If at all possible, use a dedicated car jack instead of the emergency jack.
The emergency jack is not designed for frequent uses and could sustain damage if overused. If the emergency jack must be used, do not put any body part under the car until jack stands are secured.
Be sure to place the car jack under the proper reinforced areas.
The reinforced area is located just behind the front wheels, between two bumps in the undercarrage frame.
Reference the car's manual if you require more information on how to safely jack up your car without damaging the frame.
Leave the car for about 20 minuites to allow all the oil to drain.
Once the oil stops dripping, screw the drain plug back in by hand.
Tighten the drain plug with the crescent wrench until it is secure. Do not over tighten as the plug will have to be removed for the next oil change.
The torque spec on the drain plug is 29.4-39.2 N-m (21.7-28.9 ft-lbf). Over or under tightening the plug could damage the oil pan and lead to future leaks.
Wipe off the dipstick before to remove any excess oil on it.
Put the dipstick back in the dipstick hole in the engine bay and push it all the way down.
Pull the dipstick back up and look at where the oil line is with respect to the markings on the dipstick.
The low oil line is the lower raised line on the dipstick, and the high oil line is the higher raised line. You want the oil level to be in between the two.
Because the RX-8 engine is designed to burn oil during operation, I suggest you try to keep the oil in the upper third of the fill range to avoid driving with low oil in the future.
If the oil level is too low, add more clean oil into the oil fill spout. If the oil level is too high it may be necessary to drain the oil and repeat the guide over again to avoid engine damage from excess engine oil.
