What do you guys think about the new fully sythetic oil by Mobil 1??...They gaurantee the oil to last 15000 miles or 1 year which ever comes first..

 

I think you would have to worry about the oil filter not filtering after 7500 miles.

 

I would agree that the oil filter would seem to be the limiting factor. This oil may be best suited for vehicles that are used infrequently?

 

actually they recomend just a normal filter..and they say it will last as long as the oil does

 

there's no doubt the oil will last 15k or even their existing mobile 1 will last 15k.

the filter however will not. if its doing its job right it will become clogged and require replacement... if its not doing its job right it will pass the garbage back into the oil pan

I'll be using mobile 1 (regular) when i hit 10k and change at my normal schedule of 5k (1/2 year).

ppp

 

yeah...i kinda agree with u guys...i use normal castrol gtx right now...im going to switch over to Mobil 1 (extented performance) when i hit 15000 miles...im at 14000 right now...I think i will be changing it every 4-5 K miles

 

what's the logic behind 15k before you go synthetic

 

Yeah....3Aims took the post right outta my keyboard....Why wait so long? I went synthetic the minute I hit 1,500 miles (much less waiting to 15,000 miles). ALL your highline performance cars come with it from the get go. Your break-in is just a little longer with it installed at 0 miles. That come from almost two million miles of synthetic experiance on my part. JBX

 

it doesnt hurt to wait till 15000 miles...better safe than sorry...i just let it break in for 15000 miles

 

With the OEM filter? definitely. It is the size of a tiny teacup. Use a real filter like this http://ecat.arvinmeritor.com/smartlink/?partnum=PL14610
and you should have no issues with 15000 miles of service. I do the 7500 mile interval now, but I saw this M1 extended stuff in WalMart for $23 for a 5 qt. jug. So for $28, I can go almost a full year. Damn good.

 

i use the PureOne oil filter by puralator

 

Hey all,

I actually want to start changing my own oil on the 2005 G35. However, I have been reluctant because it sounds and looks difficult.

Reading the owner's manual gave me a boost of confidence that I could actually tackle this.

People that have experience in changing oil for G35 (especially the 2005) what items will I need for the maintenance?

Example:

Engine oil (what brand, type, etc.), gloves, pan, type of filter, etc.

Thanks!

 

Birdhouse,
I was a little reluctant to change teh oil since the other posts I read were soooo detailed. Here's the way I did it.
Jack the car up on the drivers side usign the hold down hook loop, place a jack stand behind the jack (just in case). This should give you enough room to remove the screws holding the cover on.
REmove the drain plug and filter. I let the old oil run for about 3-5 minutes (enough to drink a beer). Install the new filter and drain plug and put in about 4qt of oil.
I then re-installed the engine cover and lowered the car.
Check the level when the car is sitting level again, add oil as needed, run the motor and re-check.
Easy as can be and saves you a good 20 bucks or more.

decreigh1,
Your making too big a deal and too much work out of your oil change. Just put in 5 Qts of oil, run the engine, let it sit for a few minutes then check the dipstick. Now you know that you have the correct amount of oil and this gives you the opportunity to infarct confirm that the dipstick is calibrated correctly.

As far as the Mobile 1 goes....I'm of the belief that the filter is the weak link in the system, therefore I like the 3-4000 oil change interval. Using straight Mobile 1 would be a waist. Quaker State makes an oil that is a mixture of synthetic and mineral oil, or you can use a mixture of say 2 Qts Mobile 1 and 3 Qts mineral oil.

 

im not sure if this is true for gas engines but in my diesel class we were told to NOT mix mineral and synthetic oils. and just for some extra unneeded info. amsoil has a dual system that goes 25k miles or 1 year with two filters and amsoil synthetic oil.
