As I approach 100,000 miles here within the next few months I'll be swapping out fluids. I was wondering if a high mileage oil would be recommended over a synthetic oil on a car with this amount of mileage? I'm thinking about running 0w30 Castrol Edge or a generic high mileage oil. Thoughts?

What oil have you ran in the car up until this point?

That's just it I have no idea what oil the previous owner had in the car up until the point he sold it to me. I left a message today with him so that I can gather a little more information from him regarding past oil that was being used and if he recalls when the trans/radiator fluids were last replaced. If not, I'll be doing that all @ the next oil change interval. Can the Castrol GTX high mileage go 5,000 miles between changes?
Edit: Just got off the phone with the original owner and he dug through some receipts and all he could tell me was that it was listed as, "synthetic blend 5w30". He didn't give me a brand or anything like that. The fluids were done, "a long time ago". Which didn't really help me out at all with an exact mileage number. Do you think I should stick with synthetic but reduce down to the 5w20? Or switch over to conventional high mileage motor oil 5w20? thanks, much appreciated!
Yep, Castrol GTX HM can go 5000 between changes. Very robust oil considering the price.
I've read over @ BITOG that all high mileage oils contain some synthetic.
Alright, I guess I'll make the switch over to Castrol GTX HM and call it good from here on out. Hopefully, the 5w20 will suffice for the extreme elements of Florida weather.
High mileage oil is totally unnecessary as long as your engine isn't leaking oil and is running well. It's just a marketing ploy from the oil companies. They say that a car with over 75K miles is "high mileage". Puuhhhleeeze! That's NOTHING on a well maintained Japanese nameplate car. HM oil contains chemicals similar to brake fluid which swell-up your engine seals/gaskets to stop leaks. You can switch to synthetic at any time on a good running engine with no leaks. Before you change the tranny fluid, check it first to make sure it isn't super dirty and black or gooey like tar. If it is DO NOT change the fluid...just top it off. If the fluid is pink or red, but just somewhat dirty or grayish-pink/red, you can/should do a flush (I use synthetic AMSOIL ATF). Change the strainer out as well (Beck/Arnley makes a good strainer/gasket kit). Don't listen to the Toyota dealer when they tell you to never flush the fluid or to never change the strainer. They want you to come back and buy a new tranny or better yet (for them) a new car. Flush out your power steering fluid (it's the same fluid that goes in your tranny). If you're using petroleum-based motor oil, do not use the 0/20 or 5/20 unless you're driving in a VERY cold climate. 0/20 or 5/20 oil was pushed on carmakers because of "environmental" and political reasons. It doesn't provide enough protection. I'm using synthetic AMSOIL 0/30 which replaces any 0/30 or 5/30 or 10/30. You can use a 5/20 if it's synthetic, but I think you should use 5/30 synthetic or regular. If your car has 100K miles and has the original spark plugs, change those out. Check your cabin air filter as well. It's easy. I hope this helps you!

Hey, thanks for the tips. Yea, the climate currently is getting hot and I don't mind spending more $ to get a good synthetic oil to use in the car. Maybe I'll go with the 0w30 Castrol Edge Sythnetic. Unless a huge impact would be made by going with the 5w30. I just feel this is one of those areas that could be hugely debated yet it's a simple fluid change. I'm not using a formula 1 car just a DD that I want to last another 100,000 miles. Tranny fluid didn't look bad at all. I pulled the dipstick the other day and it just looked a little darker than newer fluid would but nothing black, burnt, or tar like. The A/C cabin filter was replaced and it looked to be the original with 96k miles on it...haha. My what a difference in appearance that was. Keep the advice coming if you have any more. Much appreaciated!
Castrol Edge is extremely thin according the CST rating in the specs sheets. Not the best choice in a hot climate like Florida.
A good suggestion would be to get a high mileage synthetic like Valvoline Maxlife Synthetic. Comes in both 5W30 and 10W30 if you want something thicker.
Or you can get Mobil 1 High Mileage 5W30 @ Walmart for pretty cheap.
John Anthony is right in saying that 75K on these engines is nothing, but the additives in the high mileage oil will help reduce the rate of metal wear even further. Only a certain few high mileage oils contain swelling agents, while most others have the ideal conditioners to prevent deterioration of old seals that reduce oil burn off.

In Florida, 5w-30 should be fine, no need to use 0w-30. If you only go 5000 miles on a fill, any name brand oil will do, even dyno, if your driving is not severe.
You don't really need a 0/30 oil as hotter weather is approaching. My synthetic Amsoil 0/30 actually takes the place of 5/30 and 10/30, but with other brands of sythetic a 5/30 would be just fine. 0/30 was really made for COLD climates. Also, make sure to flush the tranny fluid before it gets super dirty. When you changed your cabin air filter, you didn't use a screwdriver, did you? Before you use synthetic oil, make sure you have no leaks, because it's expensive and all your money will leak out with the oil. If you have leaks, just use a good regular type 5/30 until you get the leak fixed. What oil filter are you using?

Yes, no tools needed to replace the cabin air filter. Just squeeze the sides of the glove box and pull out/down. Piece of cake! I changed the cabin air filter on my wife's 2006 Hyundai Elantra. What a pain in the neck! The Corolla was MUCH easier. Same difference between the two cars when replacing headlamps --Corolla easy; Hyundai pain in the butt.
Re: High mileage oil.....I never used it on my previous car ('96 Nissan Sentra) and obtained over 348K miles with ZERO internal repairs on the engine. I used synthetic oil (Amsoil). That's it! I have every intention of getting at least that many miles on my Corolla. Also, what oil filters are you guys using??

I also run Amsoil 5w30 in both of my Corollas. I did change over to the Mann filters and change every 7500 miles. The AO filters are NOT being used on Toyotas as far as I know any more. I had one plug totally at about 17000 miles. Not cool to run unfiltered oil the rest of the way. I like their oil tho. I would only go to a high mileage oil if I had a worn out engine ready to die. Just run a good oil and change it and the filter regularly. I agree on the gimmick comments.

Do you think I should stick with synthetic but reduce down to the 5w20? Or switch over to conventional high mileage motor oil 5w20? thanks, much appreciated!
