5w50 is harder to source and a lot more expensive. Its kind of like a boutique viscosity. The 5w40 European and HDEO variety are usually at Walmart or can be ordered from their website. When we talk about 5w50 is more along the lines of an extreme application like track racing or in a heavily...

I threw out the old plugs. I can tell you on a non-turbo Ford 3.7 V6 when I changed the plugs at 80k they looked to me like they could have kept going until 100k miles. The plugs I took out of the 3.5 Ecoboost looked like they got cooked quite literally.

A 26 year old vehicle will probably need a lot more replaced than the hoses. Hard metal lines can corrode. etc. The best idea is to sell it to CoPart and get a newer vehicle. It will cost more to repair this one than its worth. I can imagine it needs all kinds of things.

At 60000 miles I took the stock Motorcraft spark plug out and it looked terrible as if the engine was eating the plug. I contacted a performance shop which replied back saying they would suggest changing plugs as soon as 20k but not more than 40k. So I went with NGK Ruthenium HX. The...

Gear boxes usually hold between 1 to 3 quarts of fluid which isnt a lot and the fluid is oftentimes not changed or only changed once. So if you asked me do I want it filled with Valvolines regular formula or its premium formula for a few dollars more...of course I will go with the premium...

The thing is in the past I did have severe differential issues and keep in mind 75w140 was the gear oil viscosity suggested over 20 years ago. The manufacturers now suggest 75w85 mainly for fuel economy purposes. As a result of past problems which were time consuming and expensive the moment a...

On this website many people have concluded that Amsoil Severe Gear is the best gear oil available. I have no reason to dispute that claim...until now! I just discovered Valvoline Extended Protection! Now lets discuss if its truly the best...I can already see the marketing...2.5x better! Oh.man!

0w20 and 5w30 are oils created to save on gas and it does save you 1 to 2%. The 40 weight oils are better in every way except for saving on gas.

There has always been a solution and that is Amsoil. Everyone here seems to think its a scam...its not.

The police SSV Expedition came with Load E tires. I am guessing a loaded down police vehicle and there is a need for tough tires to resist nails, go offroad, jump medians etc. Now the Active model comes with Load E. Here are two tires I found by Michelin for this vehicle.

I noticed that Ford started shipping the 2026 Ford Expedition Max with 18 inch Load E tires. I have never driven on or experienced Load E tires. Please let me know your thoughts in terms of comfort, wear and overall reliability of these Load E tires. I have read the ride is a bit stiffer than...

I go with Castrol, Mobil 1 or Valvoline...whichever is the cheapest. I think the SuperTech version is 0w40...they dont make a 5w40 and its API SN. You want at least API SP.

The Navigator has been V6 Ecoboost since 2015. Prior to 2015 it was a V8. I am now on my 4th Navigator. Since Ford started using the Ecoboost its been a long road of problems with everything finally fixed in mid-2022. Whether you use Amsoil or not you should go with a 40 weight oil like...

Thanks for posting this. This sample is a great example. Over the years Ive tested many oils and all of the various oils sold at Walmart fall into the 8s in the viscosity section after just 3000 miles when it comes to the Ford 3.5 liter Ecoboost High Output engine. In your 2 samples the...

Like said...simply look at the library on here of used oil analysis. When I look at Amsoil used oil analysis it seems better at staying in grade versus Mobil 1 used oil analysis.

There are plenty of reports on Bob website for different Ecoboost engines. Most use the 5W30 variety. This one is from oil analyzers. Feel free to use the search function or Google to find more reports. Amsoil is not immune to dilution effects but it stays in grade and resists dilution...

Im sure glad you asked! Here is a report of the virgin oil and a used oil analysis of a early production problematic 2018 Lincoln Navigator L (Ford 3.5L Ecoboost High Output). As the report suggests heavy work was done to the engine. This is 5w30 but I suggest the thicker variety 0w40 for...

Thats probably a 2014 Suburban. After 2014 there has been a lot of issues. Lifters and transmission seem like ongoing problems. The 2015 and 2021 Suburban were the worst in terms of reliability. If you get a 2026 GM truck Im betting it will be the most reliable since 2015. Still I wouldnt...

Just a note for the thread...Ive been running the 3.5 Ecoboost since 2018...70000+ miles a year...half a million miles. Ive done a lot of different oil tests over the years and the results every time is the engine breaks the viscosity down. For 5w-30 its broken down to a 5w-20. 5w-30 oils are...

In the 2018 to 2021 versions of the 3.5 Ecoboost there were timing chain problems as well as other issues. So I wouldnt chance it with 5w-30. I would go with 5w-40...Mobil 1, Castrol, or Valvoline. Quaker State has a 5w-40 as well. Even in new 3.5 Ecoboosts for long term reliability I...
