Just to let you know, new car warranties aren't based on arbitrary recommended drain intervals, with the keyword being, "recommended", not required. In the U.S., per the Federal Magnuson Moss Warranty Improvement Act, an oil can have 16 gazillion miles on it without being changed and if there is a part within the engine that is normally covered under warranty that has failed, for the warranty on that part not to be honored because of the oil not being changed, it has to be proven
, (and not just suspected or guessed), that with the oil not being changed and not suitable for continued use that is was the direct cause
of the engine part failing. If that can't be proven, then the engine warranty must be honored. Dealerships generally don't want motorists to know this, as they'd lose money on oil changes of course. In my opinion, that's not ethical or moral and that equals bad business practices.
Using AMSOIL synthetic motor oils, my cars always go at very least 25,000 miles or one year without needing to change the oil and for 25+ years I've always had great results, as have all my customers. There's no need to allow engine wear and tear to occur using a lower performing oil for the vehicles first part of its life. AMSOIL Signature Series oils will provide the best possible protection for that expensive engine and save you money in reduced maintenance costs and improved fuel economy. With my own daily driver, I save over $300 per year in fuel costs. If you're still uneasy about using extended drain intervals, you can change the oil at whatever interval you wish. You are under no requirement to keep the oil in the engine. I'd suggest we do an oil analysis on that oil though before you toss it out and I'm confident you'll find it is in very good condition and suitable for continued use.
If the oil doesn't need changing, then there's no benefit to changing it, no more than replacing tires or brakes, etc., when they are only halfway worn out, aside from the dealership having the benefit of taking your hard earned money. Of course we don't need or want to do that.
For your 2010 Toyota Corolla, equipped with either the 1.8 or 2.4 litre engine, the Toyota recommended viscosity is 0W-20, which is a synthetic oil.
AMSOIL Signature Series Synthetic Motor Oil delivers extraordinary lubrication in all types of automotive gasoline engines. By combining industry-premier synthetic technology with AMSOIL premium additives, Signature Series Synthetic Motor Oil exceeds the higher performance demands of modern engines. The Signature Series 0W-20 has a pour point down to -65 deg. F., (-54 deg. C.). and has a recommended/warranted drain interval of up to 25,000 miles or one year, whichever comes first With the sometimes extreme cold experienced with Canadian winters, an oil with a very low pour point will perform better in the cold, providing better lubrication, easier winter starting and improved fuel economy. I'll extend to you or any Corolla Forum members, wholesale prices and this oil has a wholesale price as low as $7.74 per quart, U.S. The retail price is $10.55 per quart.
