I live in South America, and I have questions regarding the type of API oil my pick-up truck should use. I have a Nissan turbo diesel pick-up truck, the Frontier NP300 D23 (YD25DDTi engine) this truck is sold everywhere but in the US. The recommended viscosity, and the one I use, is 5W30. Where I live, the diesel fuel has more than 15ppm of sulfur (around 50ppm) -Nissan's user manual for South America, says to use API SL, SM or SN engine oil, and according to API, these are gasoline engine oils. https://www.api.org/products-and-se...
-Nissan's user manual for Thailand (but for the same truck and same engine) says to use only API CF-4, which is a diesel engine oil, but according to API that type of oil is OBSOLETE (Not suitable for use in most diesel-powered automotive engines built after 2009)
(BTW, Thailand also have more than 15ppm of sulfur in their diesel fuel)
So why does Nissan recommends a non diesel engine oil for South America and they also recommend an obsolete diesel engine oil for Asia? Are they just doing copy & paste on their user manuals? Or they want their engines to go sooner than they should be? I'm confused with all these Nissan nonsense, no wonder they are doing bad all over the world, Renault has lost 4 billion this year because of them...
API doesn't recommend using newest standard for diesel engine oil the API GK-4 if you have more than 15ppm of sulfur in the diesel fuel... So, what type of oil should I use then? europe.autonews.com/ automakers/ renault-will-take-4-billion-hit-nissan-losses
