I saw @Drewby83 say that he hadn't heard back from Fram after telling them about his filter issues, so thought we should record in one thread what response members have had from them. Let me start. I told Fram customer service that 2 recently manufactured XG2 filters leaked oil very fast and I...

I have tested 5 Fram Ultra XG2 filters for whether they leak between the leaf spring and end cap. Here is a summary of the results. In separate posts below are pictures of the test results. Manufactured January 13th 2021 - should have seal between the end cap and leaf spring NOT a leaker...

A while back, I made an estimate of what the Brand Ranks testing would look like in efficiency terms. At the time, there was one factor that was unresolved because I didn't have the data and couldn't get my head around how it would affect the calculation. That factor was the ratio of test dust...

This is from March 2023. Nice to see the construction and media similarities and differences in the size tested by Ascent. Only thing missing is Amsoil.

In light of the leaf spring gap in the FE and XG, is the Tough Guard now Fram's best filter? Are there any different quality concerns with the TG? If so, which competitor filter is better than a TG?

I hit a pothole and had to have my right front tire changed. After the new tire was installed, there was a big pull to the right. I swapped the front right and front left. Now there is a slight pull to the left. Should the tire shop have noticed something in terms of the rim / balancing? What...

I have a stock of transmission and power steering fluid for an older vehicle. Everything works well but I'm worried about seal leaks. Is there a recommended additive focused on that aspect of high mileage?

I am planning to look at used cars soon, and was wondering what would be a good scan tool. Was thinking that a BAFX dongle and the free versions of Carly apps would work. Any other suggestions?

The first step in an alignment is to set the correct tire pressure. If the pressure was set a few psi above or below the pressure the owner runs the tires at, would that affect the alignment in any way and if so, how and how much?

Interesting (albeit too long) videos. There are several more than these.

I have a 5 year old AAP H8/49 AGM in a car that doesn't get driven much. I had been charging it every 2 months with my CTEK 4.3 but was getting concerned with the low SOC, so I decided to put it on full time. Float voltage is confirmed as 13.6v as it should be. I have it plugged into a smart...

This ran for approximately 250 hours on my Mercedes. Slightly wavy near the seam. The o-rings were still flexible.

I have directional staggered tires that have never been rotated. The rears have worn unevenly. I am thinking that once our rainy season is over (it doesn't rain in much of CA for half the year), could I swap the rears? I read that in dry conditions, directional tires are better for high speed...

For me it's Valvoline. - Have had excellent results with Synpower. - Hear great things about Maxlife oils and will be using them next. - Zerex anti freeze is my go to. - Have had great results with their ATF. - Their DOT 3&4 is great value and works very well (I think it's a licensed product...

Quote We show that the rate of engine coolant temperature rise, readily obtainable through the OBD suite, can serve as a proxy to indicate the remaining engine oil life. We demonstrate consistent results for one vehicle under similar environmental and unloaded engine operating conditions. We...

Congrats Lewis on #6! I think that next year he will match Shoemaker's 7 and then the new rules will make getting #8 a very interesting challenge.

I just did an oil change but left an XG2 on. It has seen 17.3k miles, 3 years 2 months and 720 hours. I'm planning on another 10 months which would mean 4 years and up to 920 hours and 22.3k miles in total. Thoughts?
