Hello! As you know, the oil in our engine is very important. In Spain there is a guy with a Youtube channel that analyzes in laboratory many oils, and I have always taken him as a reference to choose my oil, I don't want to do spam, just give him credit, because the information is not mine. Here in Spain everyone is using 5w30, nobody uses 0w20, due to high temperatures. This is the information.

This is the information that I have extracted from his videos, he analyzes an absorbance spectroscopy to estimate the percentages of bases used:

I really like the Amsoil due to the fact that it uses a lot of magnesium (Mg) instead of so much calcium (Ca), to avoid superknock in case the oil accesses the combustion chamber. Boron (B) is also used as an antifriction agent, as well as a dispersant, like Redline. Molybdenum (Mb) is one of the best anti-friction additives, all have the correct amount, except Penzzoil and Mobil1. Redline uses a lot of Molybdenum, as well as Boron.

I thought Amsoil, Ravenol and Redline were the best for me, what do you think? his YouTube channel has many more reviews.

Yeah I bought a large batch of Total 0w20 at an insanely discounted price which I will unload. I’m switching to 5w30 at my next oil change. I see Costco has 5w30 synthetic at a decent price. I change my oil every 7500km (~4900mi). I have about 55,000km on my car now and it’s been 0w20. Looking forward to switching…

This is the page from the 2025 Camry Service manual from Toyota. This lends credibility to all of the statements that we are "forced" to use 0w-8 in the Camry - and 0w-20 in the GR86 due to is fuel efficiency standards and not some incompatibility issue with the motor.

Lots of choices for the Camry if you're in Mexico.
