what are you blower guys using for oil?

Too many 200,000.....300,000.....400,000 even 500,000km engines out there running around that have had nothing more than regular maintenance and conventional oil in the crank case from day one, for me to believe synthetics are to any great extent any better than a decent quality "Dino" oil. And you know what....at that kind of mileage, don't think that a synthetic run motor isn't going to need an overhaul just as badly as the next guy. Synthetics are better in extreme climate conditions I'll grant you that, but for daily use I'll stick with what works and spend the rest on Pizza, thanks :) .

Are we talking Taxi Cabs here or Mustangs:lol: I agree that in my beater I run cheap dino oil......but in a highly stressed blower motor or in my case nitrous , the extra protection of a synthetic motor oil is worth the expense. Synthetics are better in severe conditions seen in these engines:nice:
 
Taxi Cab....Mustang....Grandpa's Lincoln Town Car......different cars with the same old 4.6L engine. :shrug: .....and I’d bet with all the idling and stop and go traffic a Taxi cab contends with on a daily basis, the oil and engine are taking a lot more abuse than the odd run down the strip under boost, or on the bottle that your average weekend warrior is seeing. I’m not really sure how you’d think any kind of oil is going to protect your engine running short duration bursts like that anyway? They’re hardly subjected to any major temperature increase at all running 1320ft down the strip. And if you’re nitrous or blower set up is running that far on the ragged edge to the point where it’s stressing the mechanical components to their limit, then no amount of fancy engine oil is going to protect you against catastrophic failure at any rate. The autocross or circle track guys, I could see their being an advantage (which falls under the previous stated category of “Extreme climate & Conditions”) to using synthetics, but for the odd jaunt down the track or even spirited daily driving…….well, without getting into a full fledged argument about this, I'll just say to each their own and continue spending the extra money I’m saving between oil changes on other things. ;)

It's Ok if you're willing to gamble with your engine using inferior motor oil. I understand the short-comings of the 4.6 oiling system and feel much better knowing I have the best protection I can get. :nice:
 
wow you guys are really turning this into a debate. now i dont what the heck to yous once everything is together. maybe a middle of the road oil like motorcraft is really the best.:shrug:

Fair enough.....what you view as a gamble with inferior oil, I view as an acceptable, yet insignificant risk. And as far as seeing the short-comings of the 4.6L oiling system......I too am aware of it's short-comings, which is why I chamfered all blue printed of my oil passages and backed it with the FRPP high volume oil pump and 6-liter Mark VIII oil pan to address them. Was it necessary....probably not, but it's more reliable insurance than spending a pile of money on snake oil every oil change. ;)

That's a good job on the oiling system:nice: So you have a built motor.......why not spend an extra $2 a quart?:shrug:

Aside from not thinking it's really necessary, I don't like the idea of increased consumption and contamination that often falls hand in hand with blower engines and the use of synthetic oil. As you’re probably aware, the forged pistons require the use of additional clearance in the cylinder bore, which as you know is going to promote a little additional blow by compared to the stock slugs. If oil consumption stays reasonable with the conventional stuff combined with an oil separator and I happen to stumble across some synthetic stuff on sale, I might run it, but otherwise I’ll probably just stick with a good quality petroleum based oil and not give it a second thought. :)

I can see your thinking here:D On a stock shortblock I can see a much greater need for synthetic IMO:flag:
