mobil1 5w30esp ok for once a year oil change?

[mesmo]

I recently brought a case of 12 quarts Of mobil1 5w30esp and planning on using it on my 6 cylinder 4runner 08, with 30,000Miles as once a year oil change which would be like 15,000Mi, But I'm guessing if this would be ok since I read somewhere here that it has a relatively low TBN, something like 5.5.
Thanks

Where did you find the TBN on here? I would be interested in looking at that.

A look at the product spec sheet does not show the TBN. However, it carries a ACEA A5/B5 rating.Check the ACEA website. It seems to me that in order to have an A5/ B5 spec the TBN is around 8 as a minimum. FWIW---Oldtommy

Also Mobil 1 says the 5W30 ESP oils are made for Mercedes and Dodge diesel engines

They advertise it as a once-a-year-oil/good for 15,000 oil change interval, so your good to go.

Not a chance. The ESP oils are for modern passenger car diesel engines with particulate filters. They can't run the same OCIs in US market gasoline engines because our fuel contains ethanol, which increases acid formation, which the ESP can't deal with for too long.

If you want to run 15k mile OCIs, get Mobil 1 EP instead.

That's only in the cars that spec VW 507, Mercedes 229.51, etc.

I would go with start of winter, start of spring for my OC period - 2x/annum. Not worth pushing the OCI for the cost of a tank of gas. Just my 2 centavos, Hombre.

FWIW I'm running it with intent of a 10,000 mile OCI in the wife's 2005 Volkswagen TDI (unit injector diesel), mainly because it carries VW 505.01/506.01/507 approvals and can be had locally at Pep Boys. But I wouldn't run it long drain OCI in a gasoline engine due to the ethanol acid issue mentioned above.

I read about the TBN here https://bobistheoilguy.com/forums/posts/1078826/
Since I already buy it, I Think will use it but in 5000Mi OCI, Hope It will be fine.
