Thinking of trying Schaeffers oil...

[wtd]

in my 98 chevy truck and wife's 98 Pontiac GP. Currently I use Mobil 1 10w30 in both. Does this oil have any advantages over the Mobil 1?

I'm getting ticking in the engine of the truck at startup and even sometimes when it is hot. Since Mobil 1 is kind of on the thin side, I'm wondering if going to a thicker 10w30 would help. I don't seem to get very much ticking when the oil is new but with 3,900 miles on this current oil, it ticks like crazy untill it warms up.

For others that had noisy engines using Mobil 1, what did you switch to that quieted the engine down?

wtd, I remember your runs with Trisynthetic which weren’t too impressive. I wasn’t too fond of the stuff either, if you remember. I thought it’s barrier anti-wear package pretty marginal.

I would expect that for drains of less than 4,000 miles, you’d have better results (less wear) with Schaeffer’s 5W30 and 10W30 Supreme 7000 synthetic blend. Want hard evidence? It’s available but you’ll have to dig through the UOA section of this forum. Those two Schaeffer oils look fantastic and I’d say even better than M1 at comparable intervals ... for at least a buck less per quart.

The Mobil 1 Supersyn is definitely an improvement over its predecessor. Moly and borates seemed to have really reduced wear when this stuff is compared back-to-back with tri-syn.

“For others that had noisy engines using Mobil 1, what did you switch to that quieted the engine down?”

Red Line, 1st generation Max-Life (not the new stuff), Pennzoil … nearly any moly oil seemed to be an improvement over tri-syn. So, I’d be a little surprised to hear that Supersyn isn’t cuttin’ the mustard. Are you getting noise with Supersyn or are you still trying to use up your supply of tri-syn?

After my results so far, I'd recommend BobZoil(Schaefer) to anyone! SW MO in summer, I'd choose 10w30 over 5w30.

Bror jace,
I'm currently using the SS Mobil 1. The last oil analysis I had done was on the SS and it was pretty good. It was much better than the three previous Tri-synthetic analysis's. I wasn't very impressed with the Tri-syntheitc myself.

I'm going to have an analysis done on this current oil change, which will be my first since switching to the 10w30 Mobil 1 and the first since I did the Auto-RX clean up and maintenance dose. I haven't decided whether to change it at 4,000 miles or go to 5,000 miles. The oil still looks pretty clean at 3,900 miles. After I see the results, then I will decide whether or not to change.

Stuart,
I plan on staying with the 10w30 weight in whatever oil I decide to use.

wtd,

I think you'll find that the Schaeffer #703 10w30 synthetic blend oil will quiet your engine. The oil has a thicker viscosity than 10w30 Mobil 1 plus the friction modifier and antiwear additives Schaeffer uses will work better. You'll also get longer oil life for less cost than the Mobil 1.

In any case, it certainly won't hurt to try...let us all know your results. How often do you change your oil?...with either of they you can safely go the full interval listed in your owner's manual.

Ken,
I bought this truck new and it currently has 53,300 miles on it. I have changed the oil every 3,000 miles except one run of 5,000 miles and the current run of 3,900 miles. The first 14,000 miles I used Conventional 5w30 Mobil oil. I used 5w30 Mobil 1 from then untill 49,400 miles at which time I started using the 10w30 Mobil 1.

My first three oil analysis results using the 5w30 Mobil 1 Tri-synthetic did not support going to the maximum oil change interval which is 7,500 miles or 12 months. The first test was done on a 5,000 mile change and the other two at 3,000 mile changes. My last oil analysis done with the 5w30 SS showed better results and Terry Dyson's interpretation said I could go to 6,000 miles and retest. I'm still not sure if I trust Mobil 1 to go to 7,500 miles, at least not in this truck.

I'll see what this next analysis tells before making a firm decision.

My experience is that ordering from Tim Mills including shipping, my Schaeffer 10W30 #703 cost me almost exactly the same per quart as the 5-quart jugs of Mobil 1 at WalMart..
That said, I am planning to keep using the Schaeffer. I know there are free shipping deals in large quantities.

You can use M1 or Schaeffer's at 5000mi changes if you want to be very cautious. Unless your situation is hard on oil from short trips, oil gellers or turbo, these oils hold up fine for longer intervals.

Vettes, Minis, and Benzes are doing 12,000mi intervals on M1. I consider Schaeffer's equal to M1 with the exception of turbos. I would rather keep the base stocks in group IV and V for such high temp applications.

You really need to read neils oil analysis. Particularly where it is a tdi turbo and the numbers show excellent. What many do no understand is that schaeffers has been selling oil to turbo users. Their experience starting in the 1830s will attest that they have oils designed to run in turbos as well. Look at all the specs it meets, including but not limited to euro cars/trucks, diesels, and even mil specs. Those specs are not there because it looks pretty, it's because they have qualified those oils to be run in such.
Supreme 7000 SAE 15w40 meets and exceeds the following manufacturers’ specifications and requirements: Military Specifications MIL-PRE-2104G and A-A-52306A, API Service Classification CI-4/CH-4/SL, Global Specification DHD-1, JASO DH-1, Mack EO-N Premium Plus, Allison C-4, Caterpillar, Caterpillar ECF-1, Caterpillar TO-2, Cummins CES 20078, CES 20076, CES 20071; Detroit Diesel, Detroit Diesel/MTU Types Categories 1 and 2, International Harvester, Navistar, John Deere, JI Case, Komatsu Dresser, ACEA E5-99, E3-96, B3-98, B4-98 A3-98; Duetz, Daimler Chrysler MB228.3, Daimler Chrysler MB228.5, MTU MTL 5044 Type 2; MAN 271,Renault, Scania, Volvo VDS-2 and VDS-3, and Volkswagen VW 502.00 and 505.00.

Do you think that maybe some of those companies that have approved these oils might have turbos in any of their equipment? Come on. Look past the base stock issue as you are not seeing the whole picture. Like most, all you see, it's got dino in it. Do you really understand that their is different types of dino, and that blending pao's with dinos actually can make a better than standard dino?

Look let me explain this once again...

This is where most people fail to understand and think that the base oil used, group whatever, qualifies the oil to be ok,better than ok, good, better than good, and best depending on what base stock that is used. INCORRECT. The different groups mentioned..
group I,II,III,IV,V and so on does NOT MEAN that one is better than the other.

Base oils are classified as either

• Paraffinic
• Naphthenic
• Aromatic
• Synthetic

These classification refer to the molecular structure of the base oil, not a measurement of which is better and best.

In 94 a broad classification of base stocks was developed by the API for the purpose of creating guidelines and base oil read across performance for the licensing of engine oils.

This was used to determine min engine testing requirements when substituting one base oil for another.

This broad classification was used to identify the base stock by its composition and the methods used to refine or produce them. These classifications do not mean or imply that one group is better than the other.

Certain aspects of a group I and group II are better for natural lubricity than a III or IV.

Let's look at the Schaeffers 10w30 for example,

Solvent refined is mentioned- This helps increase the VI index, Also solvent refined base oils retain some of the natural antioxidants that are needed for good oxidation stability.


Severely raffinate hydroconverted 100% paraffin base oils- This process is where they process the raffinates by placing it into a proprietary hydroconversion reactor that saturates the aromatic and naphathinic compounds into highly paraffinic molecules. Next the lube oil factions are stabilized and fractionated in a finishing reactor to further improve the base oils VI and volatility characteristics.

The next step is the lube oil fractions undergo solvent dewaxing. After that, the final product is now a group II basestock of 105-120 Vi.

Dewaxing is used to remove wax that is in waxy raffinates in order to improve the base oils low temp operability.

Now add in polyalphaolefin (PAO) synthetic base fluids to the above. Now there is many positive things about this fluid in addition to the groups mentioned above that enhances even more the base properties of the other groups therefore you no longer are using just a group I or II but a special designer group mix that takes many different qualities of each group and makes a better than average base stock then you add in a highly specialized performance additive package and a highly shear stable viscosity index improver
on top of the already good stable VI's, again enhancing the VI's from the 80-120 now to 150VI. As you can see, we no longer are looking at just a group I or II base oil but a base oil that's not even classified on here.

Ok, last thing... Then ad in a proven frictional modifier, Micron Moly®, a liquid soluble type of Moly that plates to the metal surfaces of the engine. Once plated, the Moly forms a long lasting lubricant film, which prevents the metal surfaces from coming into contact with each other.

Ok, what does that do, well, by reducing friction because of inherent scuffing due to shearing of the hydrodynamic process, we now don't have near the heat demand on the base oil, so then we find we're not creating as much oxidation with the base oil due to excessive heat, where as those that don't use such, will have more heat stress therefore needs a higher level of base stock to resist the offset of heat.

This combination has proven out in oil analysis to hold up as well as most all "full" synth's yet possesses better wear protection in many cases. This process is also used by LE I believe as they too do not use a full synth but a blend of gI and II oils to build their base stocks.

To learn more on PAO and other base stocks, I have a page built for more reference..
Oil Basics about base stocks

I hope this some how might clear up the mis conception that because schaeffers might start out with a lower group oil, it is not just that group but an oil beefed up on steriods which is different that what you are reading. You must read the whole tech data sheet if you're going to base info on base oils as it is explaining to you all the types of refinement and additions done to qualify the base oil to more than just a group whatever.
