I can report back here that both myself and my buddies have had no issues using either 5w-40 or 0w-40 in either the Ford Ecoboost 3.5 or the GM 5.3 / 6.2 V8. Going into the future any vehicle we get in here will get 5w-40 unless there is some odd issue which prevents that. My buddy used 0w-40...

Both are on sale right now. I did a search and found many different threads which seem to not come to any conclusions. So let me know your thoughts on which one you would choose.

Some posters on this website do not like Amsoil for their marketing but hey its the oil business. All the oil companies have their own way to market a product. I for one have always supported the Amsoil product. My only issue is the price...I thought the oil change was costing too much...

Royal Purple seems like the boutique oil of Walmart. Ive always been a little suspicious of it and understand it uses a cheaper base stock than Amsoil. Amsoil is a very well made high quality oil which doesnt spare the expense. I would run it myself but I simply cannot justify the price. The...

I noticed on the Walmart websites a while ago they were having a lot of oil sales. Just now I was reviewing PDS on various websites and noticed Castrol Edge has API SQ on there. I realized this is probably why Walmart has this oil on sale. I remember they did the same thing when API SP came...

I have been humming and hawing on going thicker for a long time. A little while back I decided to rid my garage of the 0W20 and went 5W30 because I was burning oil. Today I learned that GM has ended all debate on the topic by telling us to use 0W40 in an engine they were initially saying to...

I researched the issue and I am guessing it could not hurt to change the Vapor Canister Purge Valve. If the valve sticks open oil consumption is likely. This is a do it yourself type change and the part costs me $40 including shipping. I suggest not using Amazon because of counterfeit part...

All of the various premium oils have come down in price to under $30 for 5 quarts on Amazon and at Walmart. Im looking and wondering what is your favorite... Pennzoil Ultra Platinum Mobil 1 EP Valvoline EP Castrol Edge EP I wont include budget friendly SuperTech Advanced and Quaker State...

I was running out of the Wix XP filters I use and was going to order more. After looking at the internet I found Wix switched to a synthetic blend media. After realizing this I looked for alternatives and found that Fram has also cheapened their Ultra filter. Both the Wix XP and Fram Ultra...

My buddy told me his mechanic told him the 2021+ Suburbans burn a lot of oil. My first thought was no way! He must be talking about the diesel. I became aware recently he really meant the gas engine! After Googleing I found even the dealers are telling owners that up to 2.5 quarts of oil...

This is my collection of the SuperTech family of oils. Full Synthetic, Advanced and High Mileage. 3000 mile intervals in a Lincoln Navigator with the high output 3.5 Liter V6 Ecoboost Gen 2. Severe service livery in NYC, multiple starts per day, stop and go traffic averaging 25 mph. All oils...

All my cars come with ceramic pads. The result is when braking it feels like sponges are between the calipers and rotors. No good! So I looked for semi-metallics and all the reviews are good for Bendix. I understand about dusting and rotor wear. So I ordered some on RockAuto. Will be here...

I got on the Valvoline squeeze bottle train and got some vibrations. I went down to Walmart and bought what I used in the past which was SuperTech 75W90. It worked perfectly...no vibration.

This thread is mainly about air filters found on the Chevy Silverado, GMC Sierra, Chevrolet Suburban, and GMC Yukon. There are two air filters listed which are standard and heavy duty. I purchased both and they look exactly the same except for a prefilter on the heavy duty version. Standard...

You can go ahead and search on Google and Youtube to learn about sludge if you are not knowledgable. In "severe" and "extreme" duty driving one challenge is sludge. Sludge is the main reason I change the oil every 3000 miles. Most notably I found the best oil to be one with the most...

On the NAPA website it says they are ceramic...how are they at dusting?

Just wanted to point this out. After looking at the formulas I feel Quaker State High Mileage is more robust then Quaker State Full Synthetic...more moly and more detergents. More robust then SuperTech and other oils. Not quite as robust as the Valvoline line. If you are out for very good...

I have tested a lot of different API SP oils from the Walmart shelf and came to the conclusion that any API SP oil will have excellent iron wear results. Much better iron wear results then what I saw in API SN and API SN+ oils. However, the constant issue seemed to be fuel dilution and how will...

I am in the livery business and own multiple vehicles. I usually buy Lincoln and Ford but am being forced back into General Motors. Back years ago I had Suburbans and there were two things which I took note of. #1. The coolant bottle after 2 years leaked and looked like it went through an acid...

I installed Hellwig sway bars and could not have been happier except for a clunk on the front bar. So then I researched the issue and the Hellwig bracket/bushing combination was faulty so then I turned to Energy Suspension and wow! What a difference! It was like my Navigator turned into a...
