Greetings flash_os!

I'm an independent AMSOIL synthetic lubricants Dealer of over 25 years experience.
Using a petroleum oil in an engine that requires a superior performing synthetic oil will cause engine damage.
Your Corolla's engine came from Toyota factory assembly lined equipped with a 0W-20 synthetic motor oil and Toyota recommends all subsequent oil changes be done with the same. :thumbdown:
Mobil 1, (the second in synthetics), is a decent product, but AMSOIL synthetic motor oils, "The First in Synthetics", (tm), outperform. I provide all Corolla Forum members wholesale prices with a Preferred Customer account, so you get the unmatched performance and protection of the pioneering leader in the synthetic lubricants industry, (AMSOIL synthetics), at lower prices than for competing synthetics. I also have high performance AMSOIL Ea Absolute Efficiency oil filters, or oil filters from Wix or Mann, again all at wholesale prices.
Beware that synthetic oils are not all the same, (far from it), no more than tires, brakes, spark plugs, etc. are all the same. Message me for a price. :thumbup1:
