Synthetic Motor Oil
 
Does anyone have experience with MOBIL 1 synthetic motor oil?...Am considering using in my 2005 Pathfinder....Any problems with oil pressure, etc.?

momud 04-21-2006 11:25 AM

yeah, great stuff. pressure increases but not that dramatically on a new motor.

check your owner's manual (OM) and make sure it doesn't effect the warranty; not sure if nissan recommends it during the break in period but some manufacturers do.

The suv has 6000 miles, so it should be broke in...Warranty remains in effect, no disclaimer against synthetic oil...

I just changed my oil (05 Pathfinder LE) and put in Mobil 1 7500 Clean synthetic Blend, I have 11,780 miles on it now...thought about going full synthetic Mobil1 Extended Performance...but still am on the bubble on running full synthetic....I know it doesn't void the warranty or anything like that.....just haven't done enough research on it yet.....more than likely I will though....running the Mobil 1 full synthetic on my 04 Honda CBR1000RR and it seems to run well......so probably next oil change I'll put the Pathy on the syn........

Sounds good....I'm hoping the Synthetic will keep engine free of varnish, etc....What are the diff. manuf. techniques ( if any) that allow Porsche, Corvette, BMW, etc. to run full Synthetic from the factory and others conventinal oil?....If its just the cost, I will go with synthetic

momud 05-11-2006 12:58 PM

cost of manufaturing what? the oil or the motors? not sure what you mean by that anyway.

today's motors are better then the old ones thus they can be run on synth right off the bat. not much of a break-in period on most cars, at least the foreign ones. M1 is recommended by mercedes and bmw, not sure about 'vette. personally i really like M1 and have used it for years now but i also blend it when i put it in new to me vehicle, slowly increasing the amount of synth with every change. my pathy is not fully synth yet and not sure it will be since i am pretty hard on it when i go offroad and i like to change the fluids often. after i do my timing belt i just may go full synth though. still comtemplating. i know of quite a few folks who use amsol also and they seem to be satisfied.

as to leaks, the synth oil only shows you where they are, it doesn't cause them. you already have the holes there just dyno oil (or the sludge enyway) has them plugged up.

Actually, I was referring to the engine manufacturing, are there any manuf. diff. (diff. materilas, etc.) that allow the use of Syn. directly from the factory while others keep saying the engine needs a breakin period, makes no sense...As to the cost, I was referring to the cost of Synthetic, most of the cars that come with it are bought by people who don't mind spending the extra for Syn, wondering if the manuf. of "common" vehicles recommend conv. b/c that is all people who buy them will use (BTW, I am not one of those Porsche owners, just don't mind spending extra on my $30 grand vehilce b/c that money is hard to come by and want to maintain it to the max)

Full synth oil at 90k miles
 
Sorry, guys, just noticed this was posted under Pathfinder...

I have a 2001 Maxima and want to go to full synthetic. Someone suggested the mileage might be too high to do it at this point. Any thoughts?

momud 08-26-2006 08:41 AM

and the milage on your car would be...?


never mind, 90k, i saw your other thread: maxima/880-synthetic-oil-90k-miles.html

dre351 08-26-2006 11:30 AM

i do not think there should be any problem with using sythetic. i changed my mustang to synthetic at 80k and now has 137k and still running strong.

kogvos 04-28-2007 02:53 AM

I changed to 5w-30 synthetic (Castrol Edge Sport as it's called in Australia) at my 10,000km service. Can't say about the oil pressure but I would imagine it would be more stable than mineral. Temperature seems to be fractionally cooler but that could just be the engine loosening up, fuel consumption has improved approx 2 litres per 100km on a long run - hasn't changed significantly around town.

Car has now done nearly 24,000km and has barely used any oil - certainly not enough to top up.

Regards,

Jamie

Sorry for the slight change in topic here, but what brand oil do the dealerships use? I know they don't supply synthetic, but are the oil changes worth the money at dealerships?

mpe235 04-28-2007 01:50 PM

They don't really use anything specific. The last dealer I worked for used quakerstate for a while and then switched to valvoline. I have seen others use just about any brand you can think of. They usually use whatever they can get the best deal on.

momud 05-01-2007 11:39 AM

The dealers around here use NISSAN oil.
