2006 Nissan Altima oil consumption

No not using a synthetic oil bc I know the engine will use that quicker than normal oil! A nissan master tech told me to try castrol 10w40 and its a little better just hope it does not cause premature engine failure since the engine recommends 5W30!

OK thank you so much for your help! Also have another question to see what you think? I have had a random misfire for about close 3yrs1/2! Nissan has changed mass air flow, crank sensor, cam sensor, plugs, coils, intake gasket, ECM, all 4 O2's, both precats, head job new valves and seals! So far engine light has been off for over a yr now but it still random misfires sometimes but not enough to set a code! They end up saying that a vaccum line was crossed from the factory! I think im having injector problems but they didnt wont to listen to me! What do you think? The car is off warranty now so I would do all the work myself if anything happens! I also work parttime at a auto shop but its always good to ask and learn from a master tech or other techs good way to learn new things! Just let me know what you think when you get a chance thank you!
