Hello, I'm not going to state what I need, that would be pointless and to some another dead horse beating.
Anyone out there in the auto/truck repair undustrie that have had a lot of experience taking engines apart and rebuilding?
 
I have rebuilt about five engines over 25 yrs. I won't say I am the best but none of them blew up.

One OHC 4 cyl engine and the rest pushrod I-6 or V-8s.

Why would it be pointless to state what you need?
 
Yep. Diagnosed, repaired, and rebuilt more diesel engines than I could possibly remember. Been in this line of work for 12 years, and was rebuilding engines from day one of those 12 years. Mostly diesel engines (Cummins, John Deere, Detroit), but with lots of oddballs and automotive engines along the way.

But enough of the chest-beating. What do you have in mind?

I've been building Cats, Cummins, Detroit Diesel, stroker Chevy big blocks, Mopars and countless marine Chevy 350's. What's on your mind?
 
LOL!!!! Sorry guys..I sort of fell off the face of the earth there. Look, go no further than the oil forum and you will be amazed at the madness, the indirect answers given to questions, the false info, etc etc. And I'm not claiming to know anymore than they do, I dont. But I want to ask an oil related question to a bunch of guys who have been there, done that, and seen in firsthand.

The synthetic debate vs conventional has spun so far out of control, it's gotten pointless to even discuss. I personally lean more toward the side if error on caution, use conventional and change more frequentily thus getting contaminates out and fresh oil in. But, the advertising from the oil companies is also relentless and stupifies everyone. All of the tout their conventional to protect just fine under severe service, then they go on to suggest you need a blend for short trips, then there is the full synthetic nightmare. So what is it? You guys have been intimately involved with the internals of engines for a combination of many years. So what do you feel works best? Do you see a benefit to synethetic..(some prefer it and even change it on short intervals). Others have logged hundreds of thousands of miles on conventional with zero problems and clean engines. I live in central Illinois which gets very cold in winter, very hot in summer and my short trips are all less than 10 minutes long so the oil very rarely gets heated up for long. Most say a conventional is all I need but then what is the purpouse of synthetic if it supposedly protects so much better? Uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuggghh... !!!!!
 
KORKL,

You need to get your oil hot before shutting off the engine; the reason for that is to get all the moisture out of the oil, and to prevent carbon from building up on the valves. The engine sort of goes through a cleaning phase once it gets sufficiently warmed up.

My car has a digital water temperature gauge; so that gives me a general idea of the oil temperature. 180*F is the minimum I like to get the water temp at, but preferably up to 195*F if I can get it there. Otherwise, you can put a thermometer on your water hose and then take note of the gauge position.

I know that some people will say that's a waste of fuel if you're just going to make a short 10 minute trip, but I believe the benefits of a clean engine far out weigh the costs of fuel.

It's my opinion that even full synthetic oil won't save you from cold engine operation. To clarify further: I said "cold engine operation," not cold starts; full synthetic is still beneficial for cold starts.

Well I've taken a few engines apart, mostly saturn 1.9s with gummed rings, one with a spun rod bearing. I have no idea what oil was used or how properly and regularly it was changed before these basket cases roll onto my property.

I can recommend an oil, but only from what I read here. My ability to take something apart, find and remove carbony goo, and reassemble without knocking or oil burning does not qualify me to say "if you had done x y would never have gone down."

As far as heat cycles, I'm of the school of "as long as it warms up well at least once a week, it will boil the baddies out of the oil before it goes acidic/ gas logged."
 
So, it sounds like I really don't have an issue with needing synthetic in central Illinois in regard to cold starts since the temps typcially don't go below zero other than when the wind chill takes it that low or lower?
Or, would I still have the upper hande using the stuff and presuming it will combat the short trip fuel delution and moisture a little better than a conventional?
 
wind chill will take your heat soak, so if you stop for half an hour and come back it's practically a cold start again if it's windy... not so much if it isn't.

Otherwise it has no effect. If you stop for shorter or longer it doesn't really matter either way.

Fuel dilution is a good thing to study on the UOA and VOA boards.
