First Oil Change: Mobile 1 or Castrol Syntec?

HKYStormFront

ok, i'm gonna throw my two cents in on this one. first of all, i realize we have similar but different motors. i started changing my oil after the first 3k miles with mobil 1 synthetic 5w30. i usually changed it every 5k afterwards give or take. due to my trip to ZCON this year in the truck i stretched it a little further and ended up changing my oil right at 60k the last time (right after i got back from Tx), again with mobil 1. recently though, my engine has gotten very rough running. on the cold mornings that i've been getting up for work (below 30*) it has made loud (i can only describe it as) "piston slapping" noises. i became very concerned about it so i called the dealership here in anderson, who i've never had dealings with since i just moved down here in december. long story short they said to bring it in and they would drive it to see if they could come to any conclusions based on the sounds it was making. i was due for a oil change tho because i was at 65k miles now. i took it in this past friday evening and they drove it on saturday morning (go figure it'd be warmer that morning that the entire month of dec and jan so far lol). they couldn't hear anything abnormal. i let them go ahead and just use their regular mobil oil (non-synthetic) and let them do the oil change. i immediately noticed a VAST improvement in NVH and start up noises, even when cold.

long story short: just get the oil changed at the dealership, they will have records of it in case anything happens. the oil they use is spec'd out to work with your engine. they didn't charge me much at all.

Hey man. The main reason yours got noisy is because of M1 itself. Many cars are having noise issues and cars using oil more after people switched to M1 since they changed their formulation. If you switched to Penzoil Plat, or Castrol Edge, your engine will be way quieter guaranteed. I also used M1 a while back and moved away due to this too.

M1 is not as good as it use to be. PP is better than them. Welcome

i actually heard Uprev's rep at ZCON talking about this. b settle also recommended switching to castrol instead. but since i don't work at a dealership anymore, don't have my tools down here in SC and nowhere (except B's house) to change my own oil, i'm just gonna let the dealership change the oil for now. think my total was $27 and some change.

OP, the dealership should have ester oil on hand as some infiniti's recommend it. it may cost a little more for the oil change but it's probably worth it. having worked as a mechanic at a dealership i can give this advice: 1) become well aquainted with one service writer, i was a writer for a while as well and i had customers that came back and waited in line to talk to me since i remembered their history and treated them well. 2) if you can, meet the mechanic who changes the oil and note whether or not he does a good job. if so, call back to the dealership (to the writer you got to know) and tell them to let the mechanic know you are thankful he took care of your car and make a note that you want him to continue to work on the car over it's service life so he becomes the only one to ever turn a wrench on it. if he does not do a good job (leaves oil dripping from the draining or screws loose/missing from the engine cover) call and let the service writer know so they can make a note that you don't want so-and-so working on your car again. i did this quite frequently with my customers. it helps build a trusting relationship between the writer, mechanic and customer.
