Sythetic Oil Question...
When I change my Mobil 1 every 3k-5k depends when I have time to do it, its always pretty dark. Now my friend has Valvoline Sythetic in his car, and when he changes it, it stilll looks clean!!! He said when he used mobil 1 it was always black coming out, and his car is smoother with Valvoline? Any ideas here?

I was told if you have a secondary oilter filter it will keep the stuff out of your oil and keep it cleaner longer.
what kind of car and oil filter does your friend use?

Also, both my parents use Valvoline Durablend, and its still not as dark as mine...and they use Fram Filters...I use the Nissna filter with Mobil 1....

Is it possible that Valvoline uses some sort of different combination of synthetics that don't blacken as quickly as the Mobile 1??? Or could it just be the type of car, or like someone else said, using an additional filter might pull more junk out of the oil??? Someone here can try Valvoline in one of our cars and see what happens... I used to use Valvoline in my other cars until I bought my Max and then got Mobile oil at my Nissan dealership and then I switched to Mobile 1 shortly thereafter when I started changing the oil.

The color of oil has little to do with its ability to lubricate the engine. My Mobil 1 turns dark in a few hundred miles, whereas the normal dino oil in my 99 Camry V6 looks as good as new (I'm not kidding) after 8000 miles of highway driving. It's amazing...those Toyota engines are incredible.

Oh dear.......
Color has ZERO to do with any of it.....
why does it turn so dark compared to other name brands valvoline, castrol etc.?
I sometimes wonder why I bother trying to educate.......

does synthetic lower oil pressure because it's so thin?
does that matter?

I bought a 91 Maxima from a buddy of mine a few weeks back, and he told me that it burned a bit of oil, and to be sure to keep tabs on it. He was running dino oil in it....
I always use Mobil 1 oil and filters in my Altima, so I did the same in the Maxima. It hasn't burned a drop of oil, and I have been driving it every day to work and back, 55 miles round trip.
Oh yeah, I didn't use the Mobil 1 filter in the Maxima cuz I read someone on here that it wasn't recommended....

A test that revealed a missing an anti-drainback valve is why the M1-208 filters aren't recommended......

Depends. Thinner oil is better for cold starts, so the oil can flow quickly to all parts of the engine when it starts up. After that, thicker oil is better because once motor oil is warm, it has no problem being thin, It can actually get too thin. You need thicker oil in a warm car to deal with all the stresses that your hot VQ engine is going thru, like red-lining at 7000 rpm. You don't want your oil to be thin when your car is revving hard.

I'm not sure what it'd do to oil pressure (might increase it from easier pumping?) but I wouldn't worry about it.

How could you possibly know that? You act like you have actually researched this.
STOP REPEATING WHAT YOUR COUSIN'S SISTER'S BOYFRIEND'S AUNT'S UNCLE'S DAUGHTER'S SON'S SECOND MOTHER TWICE REMOVED SAYS AND TAKE AS GOSPEL. WE ALL KNOW THAT ONCE THE OIL IS NO LONGER CLEAR, THEN IT SHOULD BE CHANGED. THAT MEANS BI-WEEKLY OIL CHANGES FOR MAXIMAS.....

what is oil?
Back to the orgina question, it seems like Mobil 1 darkens quick but by oil anlysis its still maintaining its properties.
Other brands such as vavaline may stay lighter longer but we do not have any anysis to see if its holding up any better.
A secondary oil filter may keep the oil cleaner longer if we could get someone to try it..
Its hard to get someome to try something new when the old system works.
