Mobil Delvac 15W-40 in my '24 GR86

[Son_of_shots]

I have shifted to this oil bc of the higher I will lug the engine or even put a higher load on bearings when starting. It calls for 20wt. I changed that to 30 wt but after some thought went to the 40wt.

I originally was going to keep the vehicle 3 years but I love it so m uch I am going to keep it longer. I think I will 100% waste my mponey and to a UOA afer the oil is in 4000 miles. Just curious to see the composition of the oil.

Only 0w20 will work correctly in this engine. Anything else will cause premature engine damage, & you will not be paid on warranty claims.

@Son_of_shots Please explain exactly what engine damage will occur in this engine if 0W-20 is not used.
