Agreed on all counts. I said no way am I going with xW-20 in my 4.0 Ranger because it's easy to imagine some auto shop pulling the same thing as the other poster reported. (But I change my oil myself anyway.)The 4.0 uses 5w30 due to the design of the oil pump and it's inability to maintain adequate oil pressure at operating temperature using 5w20. That engine design comes from a V4 designed in the early 60s. It's big, fat, inefficient, and clunky when compared to the newer engines. Don't compare it to the engines in modern vehicles. It's summer now, so a 20w doesn't matter. A 50 weight is excessive. 5w20 or 5w30 is more than adequate. There's much more to engine lubrication than the weight of the oil. You not only want the oil to maintain a film between moving parts. You also want it to flow between the parts to cool the bearing surfaces and be able to reach all the components in the valvetrain.
Those driver's side plugs are a real bear for sure. Been there. I think the 2.3 engines are the same deal, at least the dual plug versions.Last night I finally replaced my spark plugs and wires on my 98 2.5L. Haven't changed them before and the #3 wire boot on the passenger side was partially melted and visibly arcing/ticking while running.
Boy, that was not fun. I had the wobble extensions, etc. so the actual plug removal and install was the easy part. One of those flex cable claw grabber tools actually worked great to feed the plug down to the socket and get it started. Getting the wire boots off #3 and #4 on the driver side sucked. I didn't have a long enough pliers and they didn't have the plastic handle covers on them. When I finally got #3 boot off, the metal inside of the plug boot stayed on the plug so I couldn't get my deep socket on it so I had a heck of a time with that. Then #4 did the same thing. Luckily, my wife doesn't mind working on cars and has small hands and came out to help.
Snaking the new wires and boots with the plastic puller handles on them was another pain for #3 and #4. It was almost impossible to get them turned into position and lined up properly. I'm still not sure I got them pushed back on all the way.
Anyway, I was up til 1am and this morning I ordered a set of 11" long reach needle and ring nose pliers, lol.
