Gasoline in Europe is very low sulfur, gas in the USA is not nearly so. See here. When gas and ethanol is combusted one of the major chemicals produced is water. This water can react with the sulfur in the gasoline to produce sulfuric acid, part of which is washed into the oil. The acidic...

2001 Mercedes Benz E320. 3.2L gasoline naturally aspirated engine with 63,000 miles. FSS (flexible service system) indicated service B in 1300 miles, changed early as oil had 12,500 miles on it. Used 8.2 quarts Mobil 1 0W-40 and Mann fleece oil filter. M1 0W-40 meets MB 229.5 which is what MB...

5W-20 should not be used in those engines. The issue, according to the people on the Explorer forums, is that the oil pump and plumbing cannot generate enough pressure with the thinner oil. For later years they redesigned the oil pump to the able to generate the proper pressure with 20 weight...

Thanks for doing this! Looks very similar to the old (red) bottle formula with high moly and high VI, differences are seems in the range of lab and sample variation. This is not the same as the big name 0W-20's and certainly very different from the M1 0W-20. I just put this black bottle 0W-20...

I put Mobil 1 Synthetic ATF in my 2002 V6 4WD Explorer at the 60,000 mile mark. The truck now has 72,000 miles and everything is working fine. This was the older Mobil 1 ATF formulation that said Mercon V on the front and had a Mercon V license. You will have no issues putting Mercon V in the...

And how many fast lube places will even stock 0W-20? Most like they'll put in something else. I would guess that many Toyota's like the 2010 Prius will not be getting 0W-20 oil that Toyota wants then to have, rather they will be filled with 5W-30. I would also guess that this will make not too...

I have a 2010 Prius with 3,200 miles on it now. I changed out the factory fill at 2,100 miles and put in Honda 0W-20 oil. I will be changing that at the 5,000 mile mark (i.e. 2,900 miles on the oil) with Toyota 0W-20 and go 10,000 miles for OCI from then on. I may do a UOA on the Honda oil just...

Toyota has upped the OCI for new cars using the synthetic 0W-20 oils to 10K. This is retroactively applied to many 2010 model year cars already purchased. See here. Rumple

I changed the diff oil in my 2002 LS Explorer twice. First change I used Lucas 75W-140 full synthetic with limited slip fluid all ready in the oil. I found that I had clutch chatter from the rear after the fill especially when cold. I changed the fluid out for Amsoil 75W-140 Sever Gear *and*...

I am probably going to change out the factory fill at 2,500 miles and put in the Honda 0W-20 for an additional 2,500 miles and then change again for a 10,000 mile OCI from that point forward (i.e. 2500 miles factory fill, 2500 miles Honda 0W-20 then 10,000 miles either Honda 0W-20 or Toyota...

Thank you so much for posting this as more Toyota and Hondas are using the 0W-20 weight oils. It is very interesting how both Toyota and Honda have oils that are high in Moly. I wonder if there is specific benefit to Moly that can't be achieved through other additives? For my new 2010 Prius, I...

I drained and refilled the transfer case in my 2002 4WD V6 4.0L Ford Explorer at 60,000 miles with Mobil 1 Synthetic ATF. Works like a charm. I would choose any good quality ATF for a tcase to replace the Mercon that was the factory fill. The tcase does have a magnetically activated, ball driven...

You caught me - I hadn't looked up the properties in a while! Mobil 1 ATF sure got scads worse - see the old properties here. Flash point 236C compared to 200C, pour point -54C compared to -41C and -cP@40C of 5190 compared to 10,040. Yuck. Rumple

Ford has a TSB to switch these trucks (F150's from 1997-2005) to 75W140 from the factory installed 75W90. The thinner fluid could cause issues such as chatter and whine or hum and Ford has called for replacement in all cases. Here.
