When engine has been off for a few days, it makes a slight knocking noise for about 15 to 30 seconds until getting warmed up (summer now). Someone mentioned it's maybe a fuel pump noise, lifter noise, but not a rod. Should I add something to my 5 W 30 oil to correct this. It's only done this since the hotter summer months are here and noticed it after car has been not driven. Thanks, Nick
