Synthetic oil in J series V6 engines.

[lilmalu]

I had that feeling running synthetic in the J series was pointless.

Pretty much we are looking for the OP at idle with the car haven been driven fairly hard and fully at temp.

Okay.  I can do that for ya.  Right now I'm running M1 5W30.  I can give you oil pressure and temperature if you want.  Is there any temperature range you want?  What other oil would you like me to recommend me trying at the next oil change?

We are looking for the engine to be at 200+D and driven for a while at that temp. Next I would do a conventional (like Castrol GTX) 5W30, or Mobil1 10W30

Paul. what should i get for fall/winter times. as far as grade of oil 5w30 or 10w30 or stay with 0w30

As Paul eluded too, I Ran synthetic oil, 5W20 for the duration of my cars 78k life, and it essentially wore the hatches completely off the cylinder walls.   I may be the worst case of this happening

interesting. how about redline 5w30? It is categorized in group 4.

Here the link

HEre what my friend discussed about

7:23:50 PM crew: group I, II, III, IV, V
7:23:57 PM crew: basicall 1 & 2 are dino
7:24:02 PM crew: III is synth derived from dino
7:24:11 PM Kenneth Pay: oo
7:24:12 PM crew: and that's most of the shit you find out there (including mobil 1)
7:24:42 PM crew: IV is PAO, true synth but non polar (doesn't clean well, just lubricates well but also doesn't create as nice of films on the metal surface)
7:24:49 PM crew: then there's V, which are ester based oils
7:25:17 PM crew: V has the highest temp ratings, most shear stable, best flow etc, just expensive
7:25:44 PM crew: then there are different types of esters . . . . redline uses polyol esters (some of the best), others use vegetable esters (so-so), others use diesters
7:26:03 PM crew: you can't have a 100% ester oil, since you need a carrier oil for the additives
7:26:27 PM crew: so usually you have ester oils also blended with a bit of group IV PAO so you can have the soluable additives
7:26:41 PM crew: anyways esters are the shit

Kevin and Misha, I got rid of your posts because they cluttered up the thread with useless bullshit. If you guys want to bitch at each other over driving habits or whatever, do it somewhere else instead of this thread. Thanks.

Pics of your cylinder walls will be up latter today......

well last month, i switch to mobil 1 syn 5w30 from 5w20 mobil 1 syn, and it feels so much smoother even in hot temp

[RTexasF]

Guys does comparing oil pressure on a "built" V-6 to a stock one have any merit? To what extent was the build? Would the build require a heavier oil?

[NVA-AV6]

^ No it does not matter since we are talking about using the same engine and gauge , I am only pointing out how the pressure changes for different oils under the same conditions......

[NVA-AV6]

I don't know if you will be able to see it in the pics, but you can see the cross hatch in the tops of the cylinders which is worn away at the bottoms, I mesured a almost .5mm (That's alot when talking about cylinders) difference from the top to the bottm and saw sighns of oil control issues developing with a couple of the cylinders. The lines running witht eh piston movement are from lack of oil on the cylinders allowing the piston skirt to scrape the cylinder walls.

damn. i ran mobil 1 syn 5w-20 in my motor for the last oil change i did. the car did run smoother but i heard some type of knocking sound when you dont accelerate enough coming off the clutch. i forgot whats its called but i heard it has something to do with the valves. anyways i never got that sound before with conventional oil. also during the summer i went to check the oil before a long trip and was surprised to see that i had almost no oil on the dipstick.

i dont know anything about oils and such but i found an interesting article on oil. i only read half the page but its very interesting to know

"The main reason 5W-20 was specified for your engine is to increase the CAFE reported to the Federal Government. CAFE (Corporate Average Fuel Economy) is the combined average fuel economy of all of a vehicle manufacturers product line."

"A common thought of consumers and mechanics, voiced repeatedly in popular online Ford and Honda forums and user groups, is that Honda and Ford "know what they are doing" and have "specified 20-weight oils for a reason".  Then they assume the reason is good, typically without questioning what that "reason" actually is.  (Not the best idea in today's world of slimy business ethics.)"

Funny, those links say exactly what I have been saying for quite a while now.......
