Mobil 1 Weight

[mwascom]

I agree with 2002BlackZ06, changing synthetic engine oils that often is throwing money away. Even the US Air Farce is getting away from the practice of 6,000 mile or 6 month oil changes. Modern oil technology has made frequent oil changes a thing of the past. All that waste oil has to be recyled (I hope) somewhere, and it's costly. My Volvo gets the oil changed at the recommended 10,000 miles. I have 137,000 Autobahn and city miles on the engine and have only used Mobile 1 10W30 Synthetic. Have never had a problem, and I cruise the Bahn at a consistent 90-110 mph.

at least im not the only one that uses Mobile 1 15-50. My Z got her first oil change at 259 miles with 10-30 mobile1 and the second(at 550 miles) and all subsequent oil changes have been mobile one 15-50. but then again i only have to deal with 2 seasons around here. summer and spring. it never gets cold but sitting in traffic in over 100 F with the ac running almost makes me cry when the oil pressure drops cause of thin oil. My only concern is that im going to blow an oil seal when I take it to the track in the next couple of months.

All this for an engine that barely makes over 1 hp per cubic inch, bla. Could run any kind of junk oil through this thing and not hurt it.

truckrookie,
You are quite correct, the Chevrolet LS series engine is such a good design and strong engine one could run any junk oil and not hurt it. We just like to pay the extra $$$ for Mobil 1 cause we have so much spare change to throw out the window. BTW 405 net horses from a 346 CU IN engine is slightly more than 1 HP/CU IN.

congrats to you dj for taking car of your car in a manner you feel best fits your experience and driving habits. i also change my mobil 1 every 3000-4000 miles. you know why--because i want to.

i don't think any owner is anal about the way they take care of their favorite vehicle. how many of us don't drive in the rain, don't let anyone drink or eat in the car, put little rollers on their cars to keep them from dragging, spend endless hours putting on zaino and spend lots of disposable income adding mods?

i am new to this forum and have tried to keep a positive attitude. i have pm'ed a number of people instead of getting involved with on site arguements. over the past week i have watched a lot of negative happenings. first frank and then don. i read the posts by don under the 'suggestion' thread just to see what would set him off. in all his posts i have never seen anything except positive comments and offers of assistance-especially with banners. to show my inexperience i didn't have a clue who he was talking about when he posted his suggestion. then read i 2002blackzo6's comments==especially the second or third one--where he referred to don as 'the allmighty' and '...doesn't mean s...to him'. now i read his post that dj is 'anal' (and by implication the rest of us who fit one of the above discriptions). and, he invites us to 'flame' him. while i think things got out of hand with don, 2002black got what he asked for from don. now this site has lost don.

thanks a lot 2002blackz06. perhaps you should review how you say things. you could have handled your 'anal' post in a different manner. but, as you say, no amount of posts or opinions will change your mind. afterall, your opinion probably carries more weight than anyone elses. of course, this is just my humble opinion.

just what the general odered 5w30..... one question though many people say the oil is good for much longer than 3500 miles but what about the filter????? ive opened many filters on dinosaur oil cars and always find goodies in them.lots of shiny stuff.... what about keeping oil for 7to 10k and chanking filter more often???just some ideas.....ill still change every 3000 to 3500 miles ......just me..grandpa taught us boys that...and i think his buick still runs

Hello corvette184

Personally I will always change my oil and filter every 3,000 miles. I drive the car pretty hard and it is real cheap insurance.

I will also change oil and most other fluids after every road track event.

Just my 2 cents. Lower vescosity oils carry more heat away from vital engine parts. They also carry heat away faster. Oil are no longer thought of as "weight". Oils are tested and the test determine the call out. It means: FLOWS like a 5; Protects like a 30.

Just an interesting passage for us to ponder from one who should really know what he's talking about. This past April our Corvette club held it's annual Dothan to Panama City Cruise, the night before we had some well known Corvette people speak and again the next day. One of theses individuals was Jim Minniker from the GM powertrain team. In a private conversation with him about the LS6 engine and upgrades the subject of oil changes popped into the conversation. He said that during testing of the LS series engines they had been run the equivalant of 100,000 miles with no oil change, just filter changes (can't remember the mileage intervals) and when dissassembled they found there was no measurable wear above that of regular oil change intervals. Although this may be true, I myself would be reluctant to use that method of engine maintenance. But i guess it does illustrate the durability of not only the engine, but also the capability of the Mobil 1 to maintain / retain it's lubrication qualities. I think the secret formula here is the changing of the oil filter, and the 1/4 - 1/2 qt needed to top off the system after the filter change. The abrasive materials are being captured and removed, and the topping off replentishes some of the oil's additives. I just thought some would like to hear about this if they didn't know about the testing already. Not trying to change peoples minds about oil change procedures, just conversation.

Interesting comments Jack, quite interesting (and apparently true).

It needs oil? Like, in the engine? Nobody told me THAT!!!!!!!

[z62jag]

I use (lots of) 10W-30

[Manteuffel]

I use olive oil. Great taste...

For cooking, you know?

hehe.

My Z is 5w30, whatever it came with. Haven't changed yet.

Here are some of my experiences from the wonderful world of Ford Probes.
I use Mobill1 0W30 on both my MX-6 and my Probe. Why? Simple:
The Probe dynoed 3 hp more consistently when using 0w30 versus 5w30. 138 hp vs 141 fwhp.
I went with Redline MTL90 on the transaxle and it added yet another ~3 more fwhp. It is bonestock and it puts ~144 fwhp from an engine rated at 164.
I've heard redline 5w30 engine oil is far superior to the Mobil1, but since I don't have numbers, I will remain silent.

Fuel economy experiment:
With 0w30 I get ~32mpg on the highway and ~25 mixed, with 5w30 I get ~30 mpg on the highway and ~23 mixed. I have been measuring this for about a two year period. Numbers are pretty consistant if I change oils.

BTW, my probe is 107k miles and I did a compression test yesterday night.
Manufacturer says a car with 70k should have between 160psi and 210 psi with 6 cranks. My PGT averaged 200, running with 0w30 for about 30k miles, about 2000 of those 30k are race track miles.

I've recorded the car consumes more oil if I choose 0w30 vs 5w30:
0w30 is 1 quart for ~1800 miles.
5w30 is 1 quart for ~3000 miles.

Draw your own conclusions.

heck with the 0 weight, put a fart can on that probe and pick up like 50 horses immediately.

Since for MOST of us, the choice is between 5w30 and 10w30 Mobil 1, here's what Mobil has to say on the two oils. It seems they (and their millions in research dollars) figure their 5w30 formulation is better for NEWER cars (with presumably tighter tolerances). They call the 10w30 oil a "Higher-Mileage Vehicle Formula".
