Hi,
The handbook for my 2007 Prado states that ACEA B1, API CF-4 of CF oil is required. I know nothing about oils so hence these dumb questions.
Is the requirement ACEA B1 Boolean AND API CF-4 etc or is it Boolean OR?
The problem is I can't seem to buy B1 oil. I can get B3 and/or B4 but not B1. From the web I understand that B1 has a lower shear characteristic than B3/B4. I am unsure whether this is better or worse. Stuff on ACEA seems to indicate that better fuel consumption would occur with B1 over B3 but what is the effect on engine life?
I am too unsure on what viscosity oil should be used. The Toyota handbook seems to indicate virtually anything would do, i.e. 5/10/15/20W - 30 or 40 or 50. Ambient temperatures here range from 10 degrees Celsius to 45 C. I often tow a van with an all up weight of 2.4 tonne.
Any help would be greatly appreciated.
