My 2007 M35 Sport is going in for it's 30 K service on Monday and I have been trying to decide if I should switch to synthetic oil or not....

I have used it in thepast on other vehicles and been happy....

Also, I do not have an Infiniti dealership close to me so I was going to get the service done at Nissan. They said they can do any service, just not warranty issues...

Anyone care to comeent one way or the other???

Thanks,

Alex

Fun: 96 Deep Evergreen Maxima, 5spd swap, Quaife LSD, cammed-VQ35, black leather interior swap, lots of other stuff

Cruiser: 04 Obsidian Black M45, black leather interior, 35% tint up front, 5% rear

I have yet to have an oil related problem w/any machine in all these 40 plus years. I think synthetic, expensive oils were created just to make us, street drivers feel better...

if you live in a place where there is snow, ice, and freezing temperatures, then Synthetic is recommended because it cannot freeze.

if you live in So. Cal like I do, good old Mobil 1 regular oil is just fine.

ps: this topic has been debated from here to Istanbul on this forum. Do a quick search and you will see some other opinions.

The best oil is always fresh oil.

I don't think your gas company makes a major difference. It's all about Octane. 91 all the way and you'll be fine (except for Arco...they are really cheap on quality).

Here is my gas station I fill up at in So. Cal: http://www.bp.com/sectiongener...28375

Synthetic is better

I'm a bit concerned so far.

I took some cleaner to the door, drain and filter area and wiped up the puddle. I'll take another look Tuesday and report back.

I've not had issues switching other cars over before but we'll see.

that's right mate^ that's what I meant

Thanks everyone,

Where do you get 94 octane from? (not that I would need anything higher than 91, I'm just curious because I have never seen anything higher than 91 at any gas stations)

That is not in California for sure ... other states have 93 available as Premium. I have not seen 94 though ...

Ummm, no, it can help. Chevron puts in "Techron" additive into their gas. Which is basically a diluted version of the stuff in BG-44K and it does keep fuel injectors cleaner tha other gas. No mileage improvements per se, but the engine runs better.

Z

Ah! I did not know that ...

I don't know for sure. You should at least use the stronger version of the Chevron Techron that is sold - there are two different bottles (I forget the exact info on the bottle).

Just don't add in more than one bottle (of the BG44K or the conc Chevron Techron) more often than every 3000 miles - only use one extra one if you have a specific problem (like engine raggedness) that you are trying to cure.

Ideally, do this additive about two tankfuls (approx 600 miles) before an oil change, so whatever may have blown into the oil is removed from the engine.
