Just Drained The Mobil 1

[JetTech]

Hi Lance, if you look on the oil sample that I posted it gives acceptable limits on the right hand side of the sheet. Other than that I think I totally missed the point of your post. Sorry, I must be tired!!!

[LanceK]

Sorry I didn't catch that part of your post.

I guess the point of the post is...does it really matter what type of oil you use?

Comparing oils seems like splitting hairs to me unless you compare regular vs. synthetic and even then it's hard to agree.

[JetTech]

Actually it does make quite a difference Lance. If you want some really good reading go to http://www.bobistheoilguy.com/. There you can read about literally hundreds of used oil samples and come to your own conclusions. Just because an oil does well in one application doesn't mean it will do well in another. There's a bunch of great reading there and will make you an oil addict like me if the subject interests you.

Also I may have got ahead of myself in one of my earlier posts concerning the use of synthetics. I've been so die-hard synthetics for so long that I think I will probably try the Mobil Delvac 1 5W-40 when I reach the 3k mile mark. I had made up my mind to just use Chevron Supreme but I doubt I'll be able to. Some habits I just can't quit. The Delvac is a gas and diesel oil and has a rock solid additive package along with rock solid used oil analysis in pretty much anything it's put in. I'll do an oil sample on it just to make sure after I put it in. I get fickle when it comes to different oils every now and then

Glad you asked........ever since I put it in the engine it sounded louder at idle, more valve train noise than what it did with the factory fill oil. No noticeable gas mileage drop or other noises during acceleration or cruise, just a whole lot of valve train noise at idle. Now that I put good old dino juice back in it all is quiet at idle now. I guess I may have to change my views concerning synthetics with what I know now concerning the Titan. I'll be picking up a couple of cases of Chevron Supreme, which by the way does awesome in oil sample tests.

The things you heard years ago were mostly true. Pennzoil has done a total turnaround over the last several years. Everything from using a highly refined base stock to an excellent additive package. It's hard to put old stories to rest but they have done it in a big way.

thanks for the info,im now at 1100 miles in my xe kc. was thinking about mobile 1 until i read your posting.i had an 01 xterra i used castrol syntec
religiously,always thought valve train sounded louder than it should. never thought possibly due to oil- i think i,ll stick with 5w30 pennzoil

I'll keep reporting back here with my oil samples so we can all see how this 5.6L is going to react with different kinds of oils. So far I give the Mobil 1 10W-30 a huge thumbs down for drive train noise. I posted earlier that I'll probably try Mobil Delvac 1 5W-40 and see how that does. That's one of Mobil's best synthetics and falls within the viscosity grades Nissan recommends.

Concerning synthetics Amsoil, Mobil 1, and Redline usually report back very good results. When it comes to semi-synthetics there are superb oil samples coming in from the Motorcraft 5W-20 and Pennzoil 5W-20. All 5W-20's are semi-synthetic anyway and hold their viscosity very well, usually better than the 5W-30's. I'll look at some more oil samples concerning the Chevron Supreme and report back which grade is doing better i.e. 5W-30 or 10W-30.

Jet,

I went to a Chevron gas station to look at the Chevron Supreme oil. On the front of the bottle it states in small letters "formulated with ISO SYN" Do you know what that terminology means? Sounds like it may be a synthetic.

I went to Sam's today and got prices on cases of the oil that the carry. I thought folks might like to know what to expect price wise.

Havolin 10w30
1 case (12 quarts)
$18.88 ($1.57 per quart)

Castrol 10w30
1 case (12 quart)
$18.67 ($1.55 quart)

Castrol 10w30
New 5 gallon jug (20 quarts)
$30.14 ($1.50 quart)

By the way, I gased up at Sam's while I was there today and paid $1.55 a gallon for 87 octane. To save $$$, I won't let my Titan drink "call brands" she drinks regularly at Sam's and does just fine.

LanceK, my credentials are an executive engineer for a research lab and my department is Special Lubrication Applications. So, I get to play in the oil and grease every day.

About the "required" Nissan transmission fluids. It may have a propreitary friction modifier that is not available in aftermarket fluids. Chrysler fluids have these types of modifiers. I still have no specs on Nissans lube requirements so this is just a maybe.

Jetforeman, I looked at your analysis. That's pretty nasty for just 1000 miles. Of concern to me is the level of copper. Do you by any chance know who designed the dual cam and timing system? Borg-Warner would be my guess and if so, this is most likely the cam bearings. I am going to assume that the cam bearings are on the far end of the oil system from the pump. This is most likely why Nissan recommends dino as synthetics don't stay on the job after the pump stops. Synthetics have great pump rates but that same property means that it flows off of parts just as easily as it flows to them. Dinos will leave a residual coating that protects until the pressure gets there.
You also stated that synthetics are mineral based. PAO basestocks are gas to liquid technology. Gp III basestocks are liquid AND gas to liquid technology. Ester are reactive acid based. I expect the future is in esters as they are far more stable, need fewer, if any, binders for the additive packages, and will handle the worst temp extremes.

IsoSyn is the process Chevron uses to purify their base stocks. It's not considered a synthetic oil, although the purification process they use gives it a very high flash point with little to no impurities. That process along with an awesome additive package makes it a sure hit.

And my Titan sees a weekly diet of BJ's fuel. I filled up last night for $1.44/gallon 87 octane. Never a problem with their fuel either.

Trapper, you sound like an Amsoil man.

Exactly, but it can and has been argued that synthetics are mineral based. After all, they didn't make the crude, they refined it.

O.K. guys, How bout Valvoline or Castrol or even Exxon for that matter?

What are oil test on these?

[JetTech]

oh yeah, and Trapper........I want your job!!!! It sounds very interesting to an oil addict like myself...
