'05 Camry oil change interval

[Marty358]

Supposedly, the oil drain passages in the block are too small or not designed correctly leading to a sludging problem. If you change at 3000 mile intervals the sludging problem doesn't occur but at higher intervals it does. My stepbrother told me about this when they replaced his 98 Camry's engine at 36,000 miles because it had so much blowby. He changed his oil every 5000 miles. Check the recalls for certain years and you will see what it is about.

Did you change the oil every 10-15,000 miles on that Cressida? What was the condition of the engine at 429,000 miles? Still run like new? Still pass a California smog test with ease?

Kathy you can change your oil at about 5,000 miles here is a good point someone made up above. If you drive a couple miles a day and don't get the engine hot water will build up in the engine causing sludge. If you drive at least 8-10 miles a day 5,000 miles is fine the dino oils today have been beefed up to run 7,500 miles and synthetic 10,000 to 15,000 miles but the secret is getting the engine hot and getting out the water that builds up when the car cools off at night this is somthing all engines do. Ever notice cars in the morning putting out a steam vapor from the tail pipe or even water coming out this is the water that just comes from the engine cooling off at night. I use Mobil one synthetic oil in my engine and change it every 10,000 miles on my 06 camry.
