Hope anyone can help me on this.

i bought amsoil signature series 5w30, then i go to another workshop to change the oil get the filter.

At my sticker the mechanic write my next oil change is +5000 only which i think its a lot of bull because last time i change with their eneos synthetic oil they write +10000 interval. and im pretty sure with this oil it could go up to at least 12000 or 15000

Could anyone confirm with me the service interval usign the amsoil signature series 5w30?

yeah saw the label that why want to confirm with knowledgeable person here , 25000 miles -> 40k km is it safe to up until that point?
or should i just keep it be around 20k km only?

what i worry about here is the oil filter is it safe to let it be until 40k/20k?

thank you for your reply
