If the enigine calls for 5w-30 then the only real reason that you switch to a thicker viscosity is to lessen oil leaks? If yes, than there is nothing wrong with that.
He 5w40 oil is a thicker oil at full operate temperatures than the 5W-30 oil.
call autozone or autoadvance and they will tell you. they have that info in the computer. it should be something thicker than 10-30
Morrison bags are better as they are 30% thicker than Tesco, 10% thicker than asda and 5% than Sainsburys'
The weight of the oil when it is cold. The 15w is a thicker oil than the 10w when it is cold.
Im not 100% sure but its a call, Yes 2t oil is SAE 30 since its thicker than ATF(SAE 20).
30 is a little more viscous (thicker) at operating temperature than 20.
It they are the same weight oil as in SAE 30 weight oil there is no difference and they are identical. 30 weight oil is 30 weight oil synthetic or conventional.
25 to 30 lbs hot idleing if it is under 10 you got problems running thicker oil will raise oil presure like 20w50 or sae 50woil.
in the winter months i found in any vehicle to use 5w-30 in the winter months being that it;s a thinner oil and run 10 w-40 in the summer being that it's thicker, cuz the thicker the oil is the longer it takes to warm up and start flowing than thinner oil does during the winter months, i made the mistake by putting the thicker oil in my truck during the winter when it really gets cold and it didnt want to start at all, i had to use a forced heater to unthaw it..
5W-30 is when it's hot. They are the same when both are cold.
oil is being burned threw the piston oil rings,valve gides ,sometimes its as sample as a pcv valve that is sucking to much.high mile cars will use more oil .Try thicker oil.if your using 5/30 oil.move it up to 10/30,10/30 change to 10/40,10/40 change to 20/50.
