This is an update to my previous posts. This 15k mile sample was taken with 115k miles on the vehicle and is listed as the 3rd entry in each row. I used a mix of Delvac1 and M1 TSUV. Fuel was ARCO ECD-1 ULSD. I am working with Terry Dyson and have been using Lube Control (LC20) in the oil and...

This is an update to my previous posts. This 10k mile sample was taken with 100k miles on the vehicle and is listed as the 4th entry in each row. I am still using Delvac 1 and running ARCO ECD-1 ULSD with Primrose 405/402 as my fuel. Below is my previous post with my new data included. This...

This is an update to my previous post. This 10k mile sample was taken with 90k miles on the vehicle and is listed as the 3rd entry in each row. I am still using Delvac 1 and running ARCO ECD-1 ULSD with Primrose 405/402 as my fuel. The only new modification is a CAT 2 micron fuel filter. Below...

A little background….. I bought my 2000 Jetta TDI 5spd last Fall with 54k miles on the odometer. The first results were from the initial baseline sample which the owner estimated had between 3k and 5k miles. The baseline sample was before any modifications. I don’t know what oil was in the car...

How about a 0w-40? Mobil1 looks like it meets the requirements. http://www.mobil.com/USA-English/Lubes/PDS/GLXXENPVLMOMobil1_0W-40.asp

I have an '00 VW Jetta TDI with 54k miles. I just bought the vehicle and the maintenance history is not complete. My plan is to run an Auto-Rx cleaning interval (1500-2000 miles) followed by a rinse interval (approx. 3000 miles) before I switch over to a quality synthetic oil (probably Delvac-1)...

The following are the latest results from my engine oil analysis and comparison of Mobil 1 0w-40, 10w-30 and now Redline 10w-30. The first two numbers are for Mobil 1 SuperSyn 0w-40 at 5k and 10k. The third and fourth numbers are for Mobil 1 SuperSyn 10w-30 at 5k and 10k. The fifth and sixth...

It might be old news but, I just noticed that Mobil 1 now has a 75w-140 synthetic gear lube. I saw it at my local Kragen auto parts. Sitting right next to the 75w-90 I have used in the past was the "Light Truck and SUV" labeled product. It also contains SuperSyn like their motor oils. I found a...

Here is a picture of my SuperPlug after a 10k interval on Mobil 1. As you can see in the picture, the magnet did catch a small amount of material. When I cleaned it off it off, what came off looked like a very fine grey paste. It looks like it is doing its job.

I just posted my results of an interesting and disturbing oil analysis in the Used Oil Analysis Section. My silicon number is quite high yet my wear numbers look really good. I have to consider that either myself or the oil analysis lab may have contaminated the sample. I sample with the Amsoil...

I have been a long time Mobil 1 user but am considering a test run of Redline. As seen in other UOA's, my concern is that oil analysis data from my first run might be skewed due to Redlines potent cleaning abilities. I will have about 30k on my engine when I start the Redline interval. From 500...

I'm not one that easily gets excited about car products. Actually, I'm usually pretty sceptical about most things I read on the net. But I wanted to share with the board a car polish I recently used with spectacular results. The company is called Zaino Bros'. I used the Z5 polish with the ZFX...

There seems to be differing opinions regarding the use of a moly grease in certain types of bearings (Friction -vs- Non-Friction bearings) Specifically, how do you grease experts feel about using a moly grease in auto u-joints?

The following are the results of my first, second and third engine oil analysis. The first numbers are for Mobil 1 SuperSyn 10w-30 and the second and third (in parens) are for Mobil 1 SuperSyn 0w-40. I used the same oil filter (Mobil 1) and ran the oil the same number of miles (approx. 4,750)for...

I am having a difficult time finding data to determine which oversize oil filter(s) works on my vehicle. The application guides at my local auto parts stores don't list the filter specifications. Can someone please look up a filter for me or steer me to a good source for the data? 2002 Toyota...
