This is interesting if its true.

Quick copy and paste, but read full article above.

Engine wear actually decreases as oil ages. This has also been substantiated in testing conducted by Ford Motor Co. and ConocoPhillips, and reported in SAE Technical Paper 2003-01-3119. What this means is that compulsive oil changers are actually causing more engine wear than the people who let their engine's oil get some age on it.

yes i agree if you run the same weight. But if you run one thicker weight of oil in a synthetic you can get a compromise between performance and protection that is acceptable to me.

Wow ...

My cousin and his very knowledgeble car friends have been telling me to stop using Mobil 1 for the last year and a half. They all say its a horrible product ... I never really believed them, and I've been using M1 in my Maxima for over 2 years!

Pretty messed up stuff ... I guess my incoming G35x won't be getting anywhere near M1 Synth!

There's another thread on the forums with test results from someone getting poor oil analysis results!

With my other car which is a Ford Taurus SHO, engine rebuilders found that there was increased cam lobe wear on cars that ran synthetic oil than ones who used regular dino oil.

Since then I have always stuck with regular dino oil and change it out frequently

The title of this thread is misleading...

Mobil 1 performed excellently throughout this test. To make a statement that "Mobil 1 actually causes more wear...." is inflammatory. You should be working for Fox News (or do you already?).

I've been following the test since inception in late 2002 and Mobil1 has surprised just about every oilhead out there with its durability and ability to protect.

Now if you meant that it appears that Amsoil provides better protection, I can see the reasons for your inference. However, that statement too must be qualified. M1 was used early on in the life of the engine, where friction between the internal surfaces would have been greater. Amsoil's testing didn't start until the engine had 31K on the odometer; theoretically there's now more "space" between the engine parts, hence less friction and less wear.

Wait... didn't I tell myself I was no longer going to participate in these (religious) oil discussions, other than my own UOAs...? I'm signing off now... feel free to disregard my remarks above.

Guys, I pulled this info off Clublexus.com. The subject as well. I just thought I post it. I use to use mobil 1 all the time before amsoil.

Help me out here...

Where in that article does it say "Mobil 1 actually causes more wear?"

I just scanned through it; i don't see where it states this.

 

Did you read the article? How is it a horrible product? Didn't replace it for 20k and a year!

If anything it says to not change "any oil" as often!

 

My 288,000 mile Q45 engine lived on 10w30 Mobil 1 from 30k - 270k about 11 years......recently changed to Valvoline 10w40 as I am changing every 6 weeks [instead of 90 days] now [every 4,000 miles = 6weeks]...........guess I'll have to tell the engine how bad I was for those 11 years. Still uses ~~ <1 quart between changes.

Wow 75-80 oil/filter changes in the last 15 years.......from 4 per year [when I didn't drive much to 8 per year now]. Same cost with less expensive oil change more frequently [timewise not mileagewise].

 

So someone reads one of those so-called "internet studies" by Bob the Internet Study Guy, gets the whole thing ***-backwards and posts a thead indicating that Mobil 1 "causes more wear, tests show." (More wear than what? Five quarts of sand? Pure PTFE? Saliva? Who knows?) Then another guy chimes in with the infamous my-cousin-the-expert-said line that agrees with the initial fallacy.

Really. Guys with any real-world car smarts are laughing hysterically. Here's a the proper, verbatim summation of Bob The Internet Study Guy's Mobil 1 test:

That's it. BTISG's biggest concern was that by 18,000 miles the oil's thickness (viscosity) had jumped, resulting in an increase in oil pressure. Not exactly an unexpected result. Considering that no one in his right mind would leave any oil -- synthetic or not -- in his crankcase for that many miles, this observation is interesting only in a theoretical sense.

Mobil 1 is an excellent synthetic oil that's been race- and street-proven for many, many years. I've used it off an on for the better part of two decades in various cars, most notably a '91 Sentra SE-R that I owned for 10 years. When I sold the car in 2001 the engine consumed no oil and zinged to its 7750-rpm rev limiter with the same rabid sewing-machine jump it had when new.

I do believe that at least one other, less-commercially-available synthetic oil may be a better product across the board (Amsoil). But Mobil 1 is, and has been, an excellent solution for severe driving conditions, owing to its stable viscosity over a much wider range of temperatures as compared with standard organic oils. It doesn't get as thick when cold and doesn't thin out as much when hot, providing better cold flow and protection against thermal shear at higher temperatures.

The poster of this thread should get his facts together before misleading other G35 owners with this garbage. The Fox News comment was apropo.

 

I heard valvoline is a better motor oil. It doesn't heat as much as mobil.

 

an additional note to all this.....i also found out that putting fine grains of sand...white beach sand being the best...mixed in with the oil ..also helps engine life...

M1 and M1 Filter from day one..on everycar....period. Last car had 160k on it...still running strong when it sold

 

Whoa... was that me up there or some mutant twin of mine? It's been a while since I felt so indignant about oil.

Although I still believe Mobil 1 to be an excellent oil, even among synthetics, my UOAs seem to indicate that my VQ doesn't like the M1. I recently ran a fill of Pennzoil dino for 4K, and when comparing UOAs against M1 for similar ODIs, the Pennzoil wins hands-down.

I still use M1 10W30 in my wife's Sequoia and use an ODI of 9K miles, and the UOA reads like a 1,000 mile interval.

So, no more Mobil1 for the 3.5L VQ V6, but my Toyota 4.7L V8 loves the stuff. Go figure....

 

how about someone make a poll about this.
i think that will do it.
