This may be old news for you, but for me, I was just noticing Auto Trak II is now in the recommended replacement fluid list on product information sheet. So, I reached out to Valvoline asking for calrification. Here's the response I got: Great news for me as it cut the cost of fluid replacement...

https://bobistheoilguy.com/forums/threads/is-this-too-much-rust-for-a-gmt360-truck.394129/ Well, I got my Saab 9-7x, a GMT360 based vehicle. The frame got some flavor - mostly looks like surface rust, one spot around the frame under the engine has more rust, but the frame is still holding. Rear...

Recently fell in love with Saab 9-7x, it uses the same platform as Trailblazer, Envoy, Rainer, etc. Pics below are sent by a private seller I'm in touch with. I have no experience with GM and framed SUV, how does this rust looking for a 2009 vehicle in Ohio? Acceptable or I should walk away?

As you can see, my transmission is sealed and filter is in the middle of two transmission cases. I can't change it due to skill and cost issue. May I ask if anyone has experience mounting an external filter for transmission? Or is such thing even exist? So far this filter has 156k miles on it:cry:

The glue behind my headline seems to fail and can no longer be adhesive enough to make fabrics stay. Any idea how to fix this? Temporary or permanent doesn't matter. Appreciate.

On last episode... https://bobistheoilguy.com/forums/threads/tapping-knocking-sound-immediately-after-oil-change-rod-knock-piston-slap-valve-train-ticking-or-else.384691/ Bought a cheap borescope from Amazon. My intention is to confirm cylinder wall condition so I can rule out piston slap or...

This is very embarrassing. I have ran Valvoline’s new 5w-30 oil for 3k miles and changed it with same oil but 0w-20. As soon as I start my car I know something is wrong. There is a tapping/knocking noise from the back of engine. This is what my engine used to sound: Good engine sound Here’s what...

I have a Black & Decker 20v handheld vacuum with a battery module made of 5x 18650 + BMS. The LG cell it uses only have 150 charge cycle life and run time is getting worse and worse. Anyone know where I can find assembled lithium battery pack with bms that along this config? Thanks.

First time to be in a Sam’s Club store, so naturally I walked around and checked their oil galley. Only found two brands - Castrol and M1. Surprise to see this one on the shelf as it doesn’t carry any ACEA license. Same price as Walmart, around $33. Two flavors are provided: 0w20 and 5w30. 0w40...

When I buy ATF on RA they always recommend Transmission Fluid Conditioner. It is obviously an attempt to upsell, but my transmission does occasionally jerks or have trouble switching power from hybrid motor to engine (Something is doing bite-release-bite-release rapidly and I got no power)...

I was doing my annual spark plug change and notice one of my four plugs had oil on threads, a first time for me. It is the plug closest to driver seat. Engine runs normal with no obvious oil consumption and coolant is clear. Coils are all dry. What could cause it & what does it imply regarding...

Hi All, Does sway bar suppose to rotate a little bit when under load, even if the busing is hugging it tight? The sway bar I have right now need to rotate clockwise a little bit to make the sway bar link fit, is it ok to use some penetrate lube on bushings, so I can adjust it by hand after...

I can't curb my curious to not asking this silly question any longer lol! After watching many auto repair memes where bad part with leaky gasket ruined everything, or customer sealed oil pan like a monster but still leaking nevertheless. So why can't car manufactures design a round-shape water...

Hi All, Recently I noticed my passenger front brake would squeeze for a second when idling out of parking slot, even if my foot is completely off the brake. This makes me worried if my caliper is about to seize. Today I tried to check how hot my rotor is after a short trip. All other three are...

This year Hyundai Mapcare announces it will stop providing navigation unit updates for my 2011 Sonata, and I don't really want to swap it for an aftermarket radio because it also displays my AC setting and other useful data. Browsing through Google I see a lot of tablets that load with Apple...

I recently short-tripped a lot and fuel dilation start showing up on UOA. I understand that gasoline in oil won't evaporate when temperature is low, but how does it get into oil in the first place? After all, on a port injection engine, the gas was injected at intake, sucked into the cylinder...

According to LiquiMoly this product seems to booster concentration of moly in engine oil. I have never used it and would like to see what it will do to my engine. Would it reduce wear on frequent short trip? How much moly ppm increase it would bring in 5 Qt. engine oil? Thanks.

Found in Wally World, left is the latest one. New package has additional highlight about 50% more wear protection under sequence X engine test. Compare to their baseline synthetic oil, that's... 10% increase. Not having dexos1 gen3 certificate yet for this oil is also a bigger bummer to me. Try...

5 Years ago I did my first maintenance at dealer after I purchase my Hyundai Sonata. 60k is a major maintenance window and I didn't want other shops to mess it up. Back then I know little about car so I just go with what the service manual says. Half an hour later the service writer came in and...

Hi BITOGers, Recently my car's speakers start quit working randomly. They work most of time but on one random day they would go silent. Having tried multiple resets, turn on/off stereo unit, didn't work. What I did notice is they usually come back after my car went over a pothole. As a result I...
