Loc: Venezuela, South America
Hello, I am from Venezuela and I currently own a 2001 Toyota Corolla with an 7AFE engine. It has almost 284k miles and its burning almost 1 qt per 1k miles. We have a very warm climate, the coldest temperature is 65F and the hottest is 100F so Ive been using 20w50 Conventional Oil in it, I know it is not the best viscosity so Im planning to use 15w40 in my next oil change.

Im 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 Im not concerned about that but I dont know if it will be safe for the oxygen sensor.

What happens if TBN is to high? Can it be bad? I know that starting TBN isnt the most important thing but is TBN retention over time that is more important but I ask it as a theorical question

TBN shouldnt be any issue for your vehicle. We have a poster on here with Corrolla with miles near you and he runs toyota 0w20 with good results.

Would be perfectly fine!
I have run everything between 10w30 and 20w50 in my car without problems or side effects, and it seems to love the 15w40 HDEO diesel oil in it now, bearing in mind both our engines have the same viscosity recommendations at least in Aus.
You could run any of those viscosities in your climate, your summer is probably similar to where I am but winters can get below freezing here and the 20w50 made for some slow winter cranks...

Wow, that is interesting, I would guess it would blow up.

The viscosity recomendation of the owners manual is very ambiguous in my car. It says that I can use anything from 5w30 to 20w50 depending of the temperatures. In the climate that I live that means I can use anything from 10w30 to 20w50.

I would run 10w-30. Thick enough to do the job, saves a bit of fuel compared to the thicker grades.

Seriously 10w-30 will be ok

Couldnt the oil consumption go extremely higher if I use that viscosity?

By the way here in Venezuela gasoline is almost free, 100 gal cost 0.3$

So enjoy a bit more power compared to the 20w-50.

Try it. If you don't like it you can always change it.

I think both you and your car will like it.

Yes it could increase consumption, but depending on the cause it could reduce it. If it does burn it faster then you can just top off with a thicker oil

I'd just run the cheapest oil you can get for it, as long as consumption doesn't go up drastically.

You have an engine that uses more oil than gas and you're losing sleep over its oxygen sensor? wink

Catalysts shouldn't be deleted for obvious pollution reasons.

This said, I had the same problem in my Corolla and ran 15W-40 for many years. Corollas like thinner oils (less sluggish) but run the cheapest thick oil because of your consumption as others said.

Here is the remedy. Unfortunately Photobucket has recently stopped the third-party hosting of images for free accounts:

Using thicker oil won't stop the oil from leaking into your engine. Fix the leak!
