Interesting post. I was going to buy an Aluminum jack that's lightweight so I can carry it around. Now I'm thinking I should get a heavier steel jack and just deal with the weight. https://www.vwvortex.com/threads/jack-tilts-when-jacking-up.7623266/

I think you found the same article I found. That's what gave me cause for concern and my question. Thanks for your feedback.

Yes, the pad will be centered on the pinch weld. And there is room for the jack to roll forward as the arm is raised. The rear tires on the vehicle will be chocked.

Here is a diagram I just made in PPT. The jack would be pushed in a bit to mate with the pinch weld (not shown quite like that in this diagram, but you get the idea).

I have very limited floor space on either side of my parking spot, so I cannot position the floor jack perpendicular to the side of the car. However, I can fit it under the pinch weld at an angle. And there is room for the jack to move on its wheels as the arm is raised. For the handle, I may...

I checked the service manual for my Land Rover LR2 and it says the runout spec is 0.003". I'm considering purchasing Raybestos Element3 rotors. I'm impressed that Raybestos indicates the max runout in their product description, but they say their rotor has Lateral runout of 0.004” or less and a...

I really don't want to give up my OEM axle for a pinhole leak in the boot or a bad clamp. I'm going to pull the wheel and make a second try for a closer inspection. This time, trans in Neutral. I'll also try jacking up the lower control arm to straighten out the drive axle. Thanks for all the...

I tried turning it but it didn't budge. You would think at that point I would have realized that it was in Park and not Neutral! So that's the obvious solution to inspect the other side of the boot. Forums like this offer that second pair of eyes that we all need once in a while. For my...

2008 Land Rover LR2. All original OEM CV axles. 168K miles. When I recently had new tires put on, they told me there was a small leak near the large clamp on the outer boot of the front left CV axle. Now it's spewing grease which is very thin in consistency, almost like oil. No clicking noises...

Yes, both of these VOA's are for the HM variants.

That's a logical explanation, but I think it's very unlikely based on what we know. Oils that we have a high confidence of containing Group 4/5 base stocks don't have this high of a flashpoint at 245C/473F. For example, Amsoil SS 5W-30 has a flashpoint of 220C/428F. And Redline 5W-30 has a...

For their 5W-30 Advanced Full Synth HM engine oil, Mobil 1 publishes a flash point of 245C/473F on the product specs. This is significantly higher than other Group 3 oils, and even higher than some Group 4/5 oils. What are they adding to achieve this impressive flash point? Could whatever they...

The VOA results are so close to be almost the same when you consider sample variance. The specs on the website show a significant difference in the viscosity where Adv (11.9) is higher than EP (10.6). However, the VOA results contradict this where Adv (11.2) is slightly lower than EP (11.4)...

Attached are VOA's for these two M1 oils. I also included docs from the M1 website showing specs for each respective oil. As of the date of this posting, Walmart is selling a 5qt jug of the Adv for $22.37, and a jug of the EP for only two dollars more at $24.37.

That's a great spreadsheet. I may download it and create a separate column for the grade (e.g., 5W-30) so I can filter on just those oils that match my needs.

@Gokhan I suspected there was a good reason for that, and you would be able to explain it. (y)

I compared the NOACK for a 5W vs 10W and was surprised by the large drop in NOACK for what seems like a small step up in thickness.

@researcher Where are you finding the NOACK for this oil? I just pulled up the latest Product Data sheet on the Castrol website and they don't report it. Neither does PQIA.

Gotcha. I thought (was hoping) there might be some clever way to tell the difference for the general case.

@Gokhan How to determine if consumption is happening by transport vs. evaporation in this case?
