Let's assume a 15W-40 HDEO , Conventional ofcourse, being used in an older naturally aspirated fuel injected gasoline engine.
Mostly easy highway driving and 90% of the times the engine is started it reaches full operating temperature.
The oil in question is API SL/ CI-4, and ACEA E7.
Would 7500km ( 4500 miles ) , or even 10.000km ( 6000 miles ), be a stupid idea?
