Find either a GOOD independent shop or a GOOD Toyota dealer who offers frequent specials on minor maintenance. I have seen and heard of far too many damaged or destroyed engines caused by the barely sentient "technicians" at the various Kwicky Boob joints. I would rather pay a few dollars more and have the job performed properly. It beats the heck out of arguing with Kwicky Boob's liability carrier when your motor gets toasted because Service Trainee N. Bred Goober screwed up something on your Camry.

Shop on the net for specials and get your dealer to match the deal. My Honda dealer does it for $10. I provide the M1 oil and filter.

Thank you guys so much for replying my message at Christmas Eve.
If I use Mobil 1 motor oil is it necessary to use Mobil 1 filter also? My dealership use $5 oil filter, but Mobil 1 filter cost around $10. Does an oil filter really make a big difference, which like switch from conventional oil to synthetic oil?

I've used the Mobil 1 oil filter upon occasion and have had UOAs done both with and without that filter, and don't really see much of a difference in the results. Unless you're planning on extending you oil changes to well beyond 10,000 miles, I'm thinking that the Mobil 1 oil filter is a waste of money.

If it is an oem filter, it's probably o.k.

I would also agree! I actually do go with the WalMart "SuperTech" oil filter brand, when I can $2.12-$2.64 per. (made by Champion Labs)
 
Just as an aside, I would go with the premium filter ONLY in the very rare case of the bypass oil filter which actually is manufactured to filter out MUCH smaller sized microns. The trade off is much lower flow, but off CRITICAL line/FLOW, obviously. Another is of course the much higher premium due to higher quality filtering materials, manufacturing costs and MUCH lower production and sales volume.

I think the Mobil 1 filter holds a few more ounces of oil than the oem Honda filter.

During the holidays I read through all the posts back to 2006 October. I couldn't make the decision whether to keep using the conventional oil or switch to Mobil 1. Some messages said switching to synthetic oil "may" cause oil leak on high milage engines. Do you consider my 03 Camry with 33000 mi a high milage car? Are there any potential dangers may happen to my car if I switch to Mobil 1?
 
I really need you guys' suggestions to make the decision in order to have a peace of mind.

33,000 miles is a relative "BABE"
 
I have a friend that has a Toyota Camry with 458,000 miles!! (mostly freeway in a daily long (obviously) commute.
 
First the good news. On late model engines NO causing of oil leakage due to switching from conventional to synthetic oil.
 
Caveats:
 
1. need to make sure there are no existing leaks that are obscured by the conventional oil. If there are, then get the source/s of the leak/s fixed. (you should anyway regardless of the conventional vs synthetic change issue) Synthetic oil is less inclined to so called "plug" minor leaks like conventional oil might.
 
2. while Toyota denies this, make sure there is no engine sludge formed already in the 33,000 miles of operation using conventional oil. The dealer or yourself can perform the inspection. If you have a good relationship with your dealer, they might even do the inspection free of charge.
 
Use the lowest viscosity recommended by your oem owners manual or technical data. So for example if it recommends 5w30 to 10w30, use the 5w30.
 
0w30 viscosity also will do (given it meets the other specifications) .
 
I would run a MINIMUIM of the oem recommended OCI like for example 7,500 miles. Most dealers in this above example would recommend 3,000 to 5,000 mile OCI's.
 
For example, I personally have no issues running (on a 2004 Honda Civic with a 10,000 mile oem recommendation with 5w20 conventional oil) 20,000 miles with Mobil One 0w20, 5w20 oil.
