Help reading oil dipstick
I'm a bit confused by the STi dipstick. I changed the oil at 2000km with dino oil. I used 4.5 qts. When I check the oil when the engine is hot, say 10 minutes after turning the car off, the dipstick reads past the full mark, and the top hole is filled with oil. If I leave the car sitting for 8-10 hours (or overnight), then the dipstick reads just over the L, and only the bottom hole is fill with oil. This has happened since I did the oil change, so I don't think I'm burning oil.
Is this normal? Did I put in too little oil? I don't understand why I'm getting two different readings.

The proper fill amount is 4.8 quarts, not 4.5. So you're already a third of a quart low to begin with. The oil is best checked with a cold engine, after sitting overnight so all the oil is in the pan and there also won't be as much up in the dipstick tube to get on the stick and confuse the reading. Make sure the car is on a level surface.

Actually the proper fill amount is not 4.8 quarts for the 04-05 wrx's and sti's. They changed the oil pan size and it only holds 4.2 quarts. Otherwise, yes engine cold and level surface for an accurate reading.

LOL, the confusion continues with the proper amount of oil for the STi. Here's an e-mail I rec'd from Subaru:

Also there may be some confusion because the capacity is shown in liters, US quarts and Imperial quarts. Only the US quart amount applies. 4.5 liters = 4.8 US quarts.

Be sure to wipe your dipstick clean before reinserting. The oil from it can get on the inner walls of the cylinder.
