Would there be any disadvantage other than slightly lower fuel economy using a high quality 5W-30 Dexos D oil in the 3.0 Duramax vs the factory recommended 0W-20 Dexos D? It had dealer oil changes at 5 or 6000 miles with factory recommended oil while under warranty. It's in South Carolina year...

I been away for a few years..MH?

Amsoil makes probably the best one, the EAO11 but it is pricey like their oils for normal length oil changes. The Mobil 1 M1-210 is what I use and it is recommended for this application. I run 15W-40 Mobil 1 Delvac "Extreme" for the normal maintenance interval while still under warranty...

Valvoline Synpower is an entry level synthetic.

Well I tried it for the first time doing a few drain and refills in a 2006 530xi someone gave me and that 6 speed ZF automatic transmission shifts much better now. Trans had 171,000 miles on original fluid likely. The super harsh downshift to 1st gear is gone too. Previous to trying this, I have...

There are synthetic labeled fluids made with low cost (minimum spec) additive packages made and sold out there. Then you have high quality mostly non synthetic fluids but with a very superior grade additive package that are better in nearly every category than a low grade "synthetic" fluid. And...

If the oil leak is due to a leaky rotational seal such as front or rear of the crankshaft, then I can say it works sometimes. The better one that Bars leaks offers says on the front of the bottle that it helps with crankshaft seal leaks, which is the one I use if I'm not ready to replace the...

I liked the fine tip design for the Denso TT plugs and have installed them quite often up until now, but the set of 4 Denso Iridium TT that I installed 2.5 years ago in a 2011 Kia Soul 2.0L were COMPLETELY worn out after 50k miles, so please be aware that these fine tip precious metal plugs may...

Expected results, really. Not really beneficial, imo, but you just testing out a hypothesis? Does engine consume oil? You tow heavy with this truck?

If your tie rods are behind the front axle, then you need to shorten the right side tie rod starting with one full turn and lengthen the left side tie rod by one full turn. This will cause the wheels to actually be turned even MORE to the RIGHT slightly and in response, you will now center the...

If you have plenty of fluid, (always have and extra liter or quart of fresh fluid), you can just open the brake bleed valve on the opposite side you are working and let it slowly bleed some old fluid out into a pan. Gravity is at work here since the reservoir is higher, it will slowly push fluid...

After all this settles out, put a lock on your tank or gate and get current supplier to call you before they come over.

What model and year Porsche? We can look up the spec for the Porsche and see if it also meets the spec for Ford (GL5). But the 75W-90 part seems to be correct for the front diff on your Ford. For the rear diff on the Excursion, I would use 75W-140.

Get the full syn or full syn HM Supertech. It's only about a dollar or 2 more ($15.65 around here for 5 qts) for the 0W-20, 5W-20, or 5W-30 versions and is Dexos 1 Gen2 rated, so probably a really decent oil for cheap at 5000 mile oci or more.

If you look at the back of a bottle of Valvoline full syn high mileage, the way they rate their oils, the high mileage oil has better wear protection. That alone would cause me to use the HM version of full syn Valvoline over the non-HM. Why would they do that anyway? I mean make the HM version...
