penzoil 10w30 dino question

[2005tundra2002yz250f]

From what I read here, Pennzoil has a high dose of moly. Im planing on switching to Pennzoil for the last interval of conventional oil. My question is with the high dose of moly, is that going to prevent the engine from breaking in? Im purpsely not going to synthetic until 5000 miles, so I dont want to dump in the Pennzoil at 3000 if the moly is going to prolong breakin. Yes, I know you can use syn at an earlier mileage, but I want to wait till 5000.
Thanks,
joe

'05Tundra, years ago, I bought into that misconception as well: a great oil will prolong or even prevent proper engine break-in.

It just doesn't seem to be true at all.

Honda's special break-in oil contains 10 TIMES the amount of moly as regular Pennzoil ... even more than Red Line.

I wouldn't hesitate to use it in your brand new truck.

Just make sure you change the oil a couple times in the first 5,000-6,000 miles to flush out the burst of wear metals which will be in the oil.

I agree with the jacenator - there is some evidence that the dose of moly may actually help with wear in....but Pennzoil doesn't really have what I call a HIGH dose....defining high as over 400 ppm or so.

So this may be the first time I've read a Q about Penn dino and break in! I don't think Pennzoil would have an issue.

PS DUDE - I hope you don't have to type your handle too often!

Thats what worries me. Honda uses a high dose of moly, and it seems the honda engines dont break in, or stop shedding break in metal until 40,000-50,000 miles. At least thats what I read here. So I do not want that, and what else can it be attributed to besides the moly? I may return the Pennzoil for another conventional oil, like valvoline. I dont think they use a lot of moly, and thats what I'm using now as a flush for the break in particles/metal. I know its not the best oil, but it will only be in there 1500 miles, as was this fill.
Thanks,
Joe

Why not just follow the advice contained in your owners manual to the letter? They tell you no special breakin period is required, nor special oil change intervals. Pennzoil, Valvoline, any of the name brand oils will be just fine for your vehicle, with no special requirements.

If you are refering to the copper, that is a engine characteristic. It has nothing to do with the type of oil. It also does not seem to hurt the engine.

The Toyota 4.7L V8 generates some of the lowest wear metals of any engine. It also seems to get along with almost any oil. If you have to change oil ever 5,000 mi to maintain warranty I believe a Full Synthetic is a waste of money. Just throw in Motorcraft Synthetic Blend 5w30 ($1.44) and have a nice 400,000 mi...

I understand this engine puts out low wear numbers, which beleive me I am happy about. I am one of those hard headed guys that wont switch over to synthetic until 5000 miles. So I dont like the idea of a lot of moly if its going to make everything "slippery" for a lack of better terms. If that was the case, I would just dump the mobil 1 in now. I'm leaning towards another dino for the last 2000 miles until I hit 5000 miles, probaly valvoline again although I know its not the best.
About the motorcraft, I havent seen a 10w30 blend, am I missing it? I'm going to stock up on mobil 1 10w30 syn for the buy 3/get 3 deal, which brings the cost to 2.40 per quart. Not bad. I'm off to get 4 cases tomorrow if it is the new g4 i keep reading about. I know they just got a shipment so maybe.
Thanks,
Joe

I think some dino's like Syntec Blend are just as slippery as synthetic. Look for dry bottles that don't have wet seams.

5w30 may be a better choice for January.

Engines break in fater than you think. With that being said I dropped my factory oil at 500 miles and ran Valvoline uo to 1501 miles then changed to Pennzoil. The lact of a strong additive base makes Valvoline an excellent "break-in" oil. Again we/me/you split a lot of hairs on this forum.
Go with the Valvoline if your worried about break-in.

It isnt supposed to be out until Spring.

Currently only 5W-20 and 5w30 are a Blend.

Thanks. I ended up dumping the Pennzoil in today at 3300 miles. I'm sure it will be fine until I get to 5000 miles, then its synthetic every 5000. At least until I get out of warranty.
