Hey I have a 89 V6 Camry with 91,433 miles on it. It was once sitting for 5-7 yrs in my garage at one time, afterwards the water pump and timing belt were replaced by toyota. I kept up regularly with my oil changes every 3,000 miles. I just started to put Castrol High Mileage 10W40 in it with a Purulator blue filter (most expensive filter). The oil change was done 3-4 months ago at 89,600 miles and today i went to check my oil and the dipstick said there was NO OIL whatsoever! I'm like WTF!!! So I defenitely didnt try to start it. I added 2 quarts of oil and it said it was near full. So today i start the car, drive it a bit, and check the oil, the dipstick said its now a little past the Full mark! WTF does the car have too much oil?? It does feel more sluggish wen i rev it..... Its been having this same problem for about the last 20,000 miles but I though nothing of it... WTF is wrong with my motor??! Its weird because it said empty once when i went to change the oil, and when i released the drain plug and 4 1/2 quarts exactly came out.....
