Wondering if anyone can advise on what oil is appropriate for older Toyota diesel engines without emission systems? Seems lots of oil manufacturers have dropped the old CF rating from their oils, I’m assuming that they still meet the standard but don’t bother to certify anymore?
Currently I use Mobil Delvac 0w40 for winter and 5w40 for summer in my Toyota Dyna with a 5L 3.0L diesel (non-turbo). Mostly use it because it’s readily available and goes on sale for a good price. Also carries the CK-4 rating which I’m sure far exceeds the demands of this engine.
The manual calls for 5w30 or 10w30 CF-4 oil but I have been unable to find any 30 weight oil that carries a CF or newer rating.
Looking at switching to Mobil ESP 0w30/5w30 as I also own a TDI Audi which uses this oil and would be much more economical to have both vehicles on the same oil. This oil carries a ACTA C3 rating which covers modern diesel engines but I have read online that ‘sooty’ engines like the older Toyota diesel engines still need heavy duty diesel oil designed to handle the soot.
Thoughts? Curious if anyone has feedback or advice or recommendations on 5w30 diesel oil to look for. Thanks!
