Sure you can, but I recommend you use exactly what is recommended in your owner's manual.
You can remove the spark plugs in your 2003 Mitsubishi Eclipse by turning the spark plugs to the left. You should use a 5/8 deep well socket. The spark plugs will come out.
how many quarts of transmission oil in 1999 eclipes spyder gs
80 weight gear oil any type will due they have a specified one from Mitsubishi if your one of those peoplego to a dealership for that tho
It should use very little engine oil if any but, the engine oil capacity is 4.52 US Qts with filter change.
5W-30 should be sufficient all year round. If you live in a very cold area geographically - 10W-30 might be better. But 5W-30 will be your best bet. Hope this helps.
The 2003 Mitsubishi Outlander runs on regular unleaded.
