I don't have a ton of experience with V8's, but I have driven and been around them enough to completely understand what you mean about the low end torque. Many of them like the 351W in my friend's Bronco will smoothly and effortlessly climb hills at those low RPMs, but that particular 5.7 Hemi/8...

Looking at this question another way, how accurate would it be to say that the gear ratio which results in the best fuel efficiency for the conditions the vehicle is operating under is approximately what will cause the least overall engine wear? In a way, that theory seems logical to me because...

Great point. I never understood how someone could think those giant gears designed to easily handle peak engine torque plus a large safety margin to account for manufacturing variances, shock loading, mods, etc will be stressed by the small amount of torque transferred while engine braking...

Exactly my thoughts as well. I engine brake every time I slow down on all 3 of my manual cars (two Civics and an Acura Legend) and it doesn't seem to affect my oil consumption at all. My worst oil burner (the 05 Civic) burns about a quart every 6K miles whether I engine brake or not. I don't...

Coasting is technically illegal in many states including the state I live in, but I have never heard of that law being enforced and I don't see how it possibly could be. And yes, some amount of coasting is required no matter how you drive. Think about it, you coast for a second every time you...

A thicker oil will flow through the turbocharger slower and therefore remove less heat, but I doubt a 0W-40 would cause undesirable effects. Correct me if I'm wrong, but in Europe, I believe the Type R calls for 0W-20 or 5W-30, correct? Since you said you only drive it in the summer and on a...

Agreed. In general, driving any given distance continuously at a fairly steady speed is going to be much easier on the vehicle as a whole and LESS likely to cause a failure than driving the same distance in traffic over many start/stop cycles and heat cycles. There are certainly exceptions...

I personally don't have an age or mileage limit. As other said, it depends on its condition, how well it was maintained, how well it's reliability (or lack thereof) has been proven both to both the owner and generally for that particular model, etc. Another important factor that I haven't seen...

Not to start yet another thick vs thin thread, but that should work fine. According to owners manuals for Japan and Europe, 5W-40 is suitable for use in all temperature ranges. That said, it obviously wouldn't be ideal for frequent shorter trips where the oil is going to be below operating temp...

That seems like as good of a guess as any considering the lack of other bearing metals on the oil sample. I have no way to know the total mileage on the engine, likely somewhere around 100K assuming I got it with 50K miles since I put about another 50K on it. JDM engines are definitely hit or...

The engine is definitely not still in break in, it's been in use since I got it in 2018. It has been apart near the end of 2022 when I changed the timing belt and some oil seals, which could explain the silicon.

Thanks for sharing! Before I installed this engine, I pulled the oil pan and checked a couple of the rod bearings and they looked very good-almost new. Also changed the head gasket and valve stem seals and gave everything a good cleaning. As of about a year ago, the compression in all 4...

A couple things I forgot to mention: 1. That engine has a large stainless steel oil to coolant heat exchanger, which I believe is brazed together with copper. I installed it about 4 years ago and thoroughly flushed it before installation, but is it possible that it's still shedding copper ions...

Good idea, I may try that. Xw-40 oils are approved for that engine in other markets, so it certainly won't hurt to try it. As I said, I don't know the mileage on this engine since I bought it used from a JDM engine importer back in 2018, but it's likely quite a bit lower than the car.

Hello all, this is my first time doing a UOA and I decided to start with my part time daily driver 2005 Honda Civic with the 1.7L VTEC engine and 5 speed manual transmission. I'm not sure of the mileage on the engine since it is a replacement from Japan, but the Amsoil Signature Series 5W-20 and...
