They have filters, picked up NAPA Gold

Will be changing the oil and filters in my dad's tractors, 1937 & 1949. The 1949 has been rebuilt. The 1937 no idea when it was rebuilt but runs strong. Thinking about a diesel 15w 40 for the 1949. The older one has been run on non detergent as far as I know. I see debate saying you...

Ran Schaeffers 10-30 for 4,000 miles in my 98 S10 4.3 Blazer. Engine had 80,000 miles on it. Oil filter was a Super-Tech. Iron 5 Chrom Nickel Alum 3 Lead 9 Copper 3 Tin Silver Titanium Silicon 8 Boron 2 Sodium 11 Potasium 23 Moly 83 Phosphorus 874 Zinc 1062 Calcium 2073 Vis cs 10.9 TBN...

Ralph, would the bypass remove the coolant assuming a small leak and thereby protect the engine from bearing wear? Since intake leaks are fairly common on some engines maybe this would be preventative method?

My dad has a 1937 John Deere Model A. This an all fuel model with a small tank for gasoline and the main tank for kerosene. The engine had to be up to operating temp first on Gas the switch to kerosene. I think the compression is about 5 to 1. He has only run it on gas since he bought it a...

Bought the Fel-Pro gaskets and read the factory repair manual info. Amazing such a minor leak can cause wear so quickly. If not for the analysis might have never known since the coolant level never dropped.

1998 S10 Blazer, 4.3L with 66,000 miles at time of oil change. The oil was run for 5,000 miles over 10 months. Schaeffers oil used for last 2 times. Looks like I have trouble with coolant. Glycol was negative but the lab said coolant additives are present causing bearing wear. The coolant...

When the cat on my 5.7 chevy plugged I hardly made it home, could barely hit 20mph. Tried it cold the next day and same result. Kind of funny my fuel mileage never changed any while it plugged up. Was getting just over 20mpg, kind of expected a drop in mileage.

Not bad numbers for 7 months and the car having under 4k miles on it. And as you likely already know that copper will continue dropping. [ June 13, 2004, 08:19 AM: Message edited by: V6 Diesel ]

Thats a pretty good looking report, I would run that oil a lot longer.

Since many manufacturers outsource many parts, are they not using aftermarket bearings? I am thinking the domestics don't make their own bearings to start with but buy from whoever the lowest bidder is. Maybe they are packaged in a OEM box but made elsewhere.

I happened to have a good supply of Schaeffers 10w-30 on hand so am running that right now. I had thoughts of running Mobil 1 15w-50 for the summer. I did try to thicken the Mobil 1 up by adding half a bottle of EP 132.

1991 Caprice, 9C1 Police package, 5.7L, total mileage at oil change was 244,600 miles, 10,000 miles on oil. No oil was added, oil level was still at full mark. Used the “brew”and FP the entire run. Oil was tested by Analysts this run, Blackstone the previous tests. First 87k miles were police...

My 91 Caprice (Cop Car) has the original green silicone hoses on it. They reputed to last a liftime or million miles from what I have read. Have another 750k to go before I find out. Replacement silicone hoses are not made for this model anymore but understand Goodyear makes a High-miler blue...

It looked like the filter was orginal. The rubber all appeared to be hard unlike the replacement so might not have been sealing tight in the air box. The Kendall appeared to be an ok dino, not great. According to the Blackstone range for viscosity it is about in the middle range and the...

2003 Olds Silouette van, 32,000 miles on van, 3,347 on oil. Just bought the van and ran a test on the dealer installed oil. This oil was in for about a month. No idea of previous oil history, looked clean inside the valve cover. Blackstone did the test. Aluminum 3 Chromium 0 Iron.... 22...

Kind of funny your description, high mileage. The UOA's on my wifes 2001 Impalla showed a downward trend in wear metals indicating it was just about fully broken in by 50k miles. My Caprice has 243,000 miles so if you have high mileage I am not sure what to call mine. I switched mine to syn...

Glad to hear there are places like yours. I do most of my own work but when I had a company car had the big sell every oil change, air filters only had 3k miles but they tried to push them every time plus all the other items. Had the exact opposite when I took the company car to a repair shop...

Back in 78 we had a bad snowstorm in Michigan. Had a car entirely covered and the drift down half the driveway was close to 5ft. My brother and I spent 3 days shoveling at least 8 hours a day. After all that the road was still not open.

Rick, Pretty good tbn if that is correct, not too bad of a report. Iron is not that high. What size is this diesel, made by Landrover? What type of power output? Wish we had more diesel options here Cheers
