A total of 3days/300 track miles. it looks like it can go another day or two before the viscosity drops to a 30weight oil. BlackStone Comments: Aluminum was well above average in the first sample from your Suzuki. This usually shows excess wear at pistons, though their maybe other sources. Our...

9 months and 6.5K miles. Total sump 8 qts. I use an amsoil bypass filter as well. TBN is way down as well. SILICON was twice as high as the last few samples which probably caused the IRON to be twice as high as the last few samples... ALUMINUM 3 CHROMIUM 1 IRON 28 COPPER 6 LEAD 0 TIN 4...

First column is SF and the second is RedLine MTL@9K miles I think I'm gonna go back to RedLine MTL. Should I worry about the high copper? Check out the Iron diff between SF & RL. ALUMINUM 2 / 1 CHROMIUM 1 / 0 IRON 46 / 25 COPPER 40 / 36 LEAD 8 / 12 TIN 0 / 0 MOLYBDENUM 3 / 5 NICKEL 0 / 0...

Anyone know why a head gasket would fall apart in as little as 3K miles (it did not overheat)? This is for a 1984 Toyota Land cruiser. Oil and coolant were mixing in an alarming rate (about a gallon of coolant was being consumed every 10 miles of driving). Not sure where it went; some ended up...

I'm running SF's SynchroGlide right now... It shouldn't be too hard to beat this report. Man oh man, I'm glad i did a UOA. ALUMINUM 1 CHROMIUM 0 IRON 25 (Avg: 92) COPPER 36 (Avg: 41) LEAD 12 (Avg: 4) TIN 0 MOLYBDENUM 5 NICKEL 0 MANGANESE 1 SILVER 0 TITANIUM 0 POTASSIUM 1 BORON 32 SILICON 18...

It's a Jeep Wrangler (4.0) with 25K miles on it. For the last few weeks the engine has been having some startup issues. If the car sits for a couple of hours or overnight, when I try to start it, the engine takes a while to start. If it only has been a few minutes between startups the engine...

Can someone explain to me how a smog pump work?

Is Redline the only company that uses the ASTM D4741 test to figure out the HT/HS value? Why? To show higher numbers? Is there a significant diff between the tests? Is it like comparing apples to oranges when compared to all others that use the D4683 test that all the other use? I'm assuming...

Here is a quote from the DYSON ANALYSIS paper by MolaKule on LC&FP: My question is, if component x evaporates/decomposes after a certain time/miles, should I notice the oil level drop on the engine’s dip stick? So if I add an initial 10 oz, after 8K miles should there be 10oz less oil in the...

Does anyone else out there get any oil consumption when they use a fuel system cleaner like Redline's SI-1 or Techron... Every time I add a full bottle of either product to a full tank of gas (19 gallons) by the end of the tank (300 miles) I get a few ounces of missing oil. It never happens if...

Every time I use a Blackstone sample bottle in conjunction with the Amsoil oil sampling pump, the bottle ends up getting crushed by the vacuum created inside the bottle. After a few pumps the bottle just shrivels up in to a raisin which makes it pretty dam hard to take a sample. I'm I doing...

Is it OK to reuse the plastic hose/tube for the suction pump or will it skew subsequent UOAs? It has a visible oil film from the last sample.

Is it possible to get engine knocking in cold ambient temperatures instead of warm ones? My reasoning is that during cold temps the cylinder takes in more air during the intake cycle (air is denser when cold; same PSI but more mass). During compression when the air warms up the cylinder ends up...

Does anyone know what could have gone wrong with this engine? See pics below: pictures

Will adding LC to motor oil effect its lubricating abilities? Much like increasing the amount of detergents does... I'm thinking of adding LC in the Amsoil S2K, it has turned in to a 40wt in only 4K miles/7months...

I got mine from: MyOilShop

Can anyone comment on Amsoil's oil precharger. They just released it and I just read about it on their site. It's an accusump wanna-be. It only has an oil capacity if about 160cc, which should translate to about ~17% of a quart. They do not mention anything about the output pressure it can...

Would Redline's high temp ATF be a better choice over Amsoil's ATF in a transfer case? I'm asking because RL's ATF should provide better gear protection since it has the API GL-4 rating. Here is a copy/paste job from RL website:
