Hello, I am from Venezuela and I currently own a 2001 Toyota Corolla with an 7AFE engine. It has almost 284k miles and it´s burning almost 1 qt per 1k miles. We have a very warm climate, the coldest temperature is 65°F and the hottest is 100°F so I´ve been using 20w50 Conventional Oil in it, I know it is not the best viscosity so I´m planning to use 15w40 in my next oil change.
I´m planning to use an HDEO that has an SN Rating which is the one the owners manuals ask for. Here in Venezuela, diesel has a very high sulphur content, I think that is important for the oil properties.
The differences that I see in the website of the brand of oil I use is that the 20w50 Conventional that I use currently has a TBN of 6 and the HDEO 15w40 Conventional has a TBN of 12.
Do you think it will be safe to use this oil? my car has a cat delete so I´m not concerned about that but I don´t know if it will be safe for the oxygen sensor.
