Do manufacturer specify the oci (x miles) considering the lowest performing oil (i.e. dino) available on the market? or do they think there is not a huge difference between conventional and synthetic
Except in some specific cases of specs requiring a Dino vs syn the OM's just spec grade and minimum API designation (SN, etc.)
That way their arses are covered when Joe Schmo puts in cheap dino from a quickie lube but the engine is still happy when a BITOG'er used a nice Syn.
I tend to agree!
The problem is it will force the bitog'er and alike to change the oil too early (with a better oil) while under the warranty period in order to meet the recommended oci!
it may be hard to convince people to use the cheapest oil that meets the spec. and to follow the recommended oci till the warranty is over and after that, you may switch to a better oil for extended oci.
