Engine decking issue(help)

OIL CHANGES ALL THE TIME Mobil one just reformulated
go to the data sheets and look at additives that will tell you if you can use an oil of any weight as the weight is just one component
in SC you can get away with lots that cold weather folks can't
you can check the specs or test yourself
take that 30 and put a cup in the fridge and see how long it takes to pour through a small funnel
do it in a double boiler to get 212 and time it
save the times
now try a 0w-30
It will pour cold or hot about the same as your hot thirty weight
there will be little difference in the hot pour times
and since most wear comes when cold when the oil is thick try and minimise my wife uses a EO heater
You probably know this but for the record
do not idle to get oil temp up water will warm but oil will stay cold like forever just drive easy and take your foot off the gas and coast a few times to suck some oil past the rings and guides even worse with a carb and the choke on
Me I live right next to the Southern California freeways and have no problem with the 0W-40 getting on the freeway and merging high speed after few blocks
