I think an API SL/CI-4 rated "diesel" 15W-40 oil will work very well in a Buick 3.8L V6 engine. Keep in mind that the 3.8L GM/Buick engine is an old design. It is still probably the most reliable engine General Motors produces for sale in the USA. I think changing the oil every 5,000 miles or six months should work just fine.

Hey I jaw an ad in the paper (car paper) for ??? year vette with 387K original miles, details said runs perfect. Long trips on the weekends, sounds sweet, and burn about 1/2-3/4 per oil change, detail records, got another play toy... something like that, anyway I'm not into cars but it was an older vette
I have a 2000 Toyota Tundra V8 4x4, I have over 170K with no mechanical problems and no noticeable oil consumption. I have always used Mobil1 10w30, or 15w50 depending on weather, and how heavy a trailer I am towing. I change it about every 5-10K as time permits, I also use mobil1 ATF, and gear oil - changing them every 20K.

WOW!!! Have you posted the UOA on this? You must have quite a trend going, maybe 5 samples so far?

1984 Ford F-150 4X4 302V8, C6 auto, owned from new.
528,456km / 328,367mi
Initial oil change at 1,000km / 600mi to Esso XD-3 15W-40 and Ford FL-1A filter. Next oil/filter change at 5,000km / 3,000mi. Then at 9,000km / 5592mi. Oil consumtion stable at about 1/2 litre every 4,000km / 2,400mi.
Compression check at 9,000km: lowest 138, highest 150.
Switched to Mobil Delvac 1 5W-40 at 9,000km / 5592mi. Would change FL-1A filter every 3 months or 5,000km / 3,000mi. Tried Fram PH-8A several times but had ruptured media and never used again.
From 9,000km / 5,592mi would only change Delvac 1 once a year. On average 25,450km / 15,813mi oil drains.
In 1991 at 298,634km / 185,562mi, put in Gulf Coast bypass filter. Started using K&N as primary filter, changed every 6 months, GC bypass changed once a year.
In 1997, changed oil at 499,018km / 310,075mi along with primary and bypass. Changed filters in 1999 (516,756km / 321,097mi) and again in 2002 (524,544km / 325,936mi).
Ran Mobil Delvac 1 5W-40 all the time. Average oil consumption was from best 1 quart every 14,000km / 8,700mi to about 7,300km / 4,536mi now.
Last summmer compression check: lowest 120, highest 135. Rear main starting to leak.
Current truck from new is 2000 GMC Sierra with Vortec 5.3. Too soon to say with only 61,000km on it. Check back in 5-10 years.

Given how long cars last today, you should have put the cutoff at 250,000 miles.
Anyway, my 90 Dodge Shadow has 200,000 miles and knocks like a diesel. I used natural oil from Pennzoil... every 3000 miles.

1994 Toyota Previa 164k (fathers)
Toyota branded 10w-30, toyota filter through 150k
Mobil1 10w-30, toyota oil filter since
1994 Acura Integra 154k (girlfriends)
GTX 5w-30, Napa oil filter
Since German syntec came out, its had half that.
SInce supertech filters were deemed good by this site, they have been used
1983 MB diesel 217k (mine, yes I know it doesnt count, but its high-mileage)
15w-40 Rotella T (through 200k)
5w-40 Delvac 1 (50%) 15w-40 Delvac 1300s (50%) (now)
100% 15w-50 mobil1 (as of net oil change, in 500mi)
Mann filter cartridge always
None of these engines use a drop of oil, nor do they leak. All start easily in single digit temperatures without block heaters (but with glow plugs cycled a few times in the diesel).

195,500 miles and still going in a 94 Impala SS RWD with the LT1 5.7L V8. I initially used Pennzoil 10w/30 dino until I noticed a reddish varnish build up. I then switched to Valvoline 10w/30 dino and it now runs clean. I have always used a AC Delco PF 52 oil filter.
Last-Z, I do not think anyone on this site would ever tel you that you need synthetic to get long life from your vechile. Synthetic makes it easier to do under some conditions. Synthetics are much better at handleing the 7500-15,000 mile or longer drain intervals recomend by some OEM's.
With the current oils on the market you could probably change every 2000-3000 miles and have a spotless engine! I know I do not choose to be under my car that much! A lot of todays cars are also runing hotter and hotter to get emmissions down. I like to use a oil that leaves very little of itself behind. It has been my experince that with my driveing habits PAO/Ester based oils work much better for me with the 7500 mile OCI.
Their are many thousand of cars that hit 300,000 miles every day that have ben ran on dino but we also see cases were they do not hit 100,000 miles as well.

Even though we've seen evidence that a car doing regular oil changes on dino can get long life, I still think a synthetic oil fed engine will maintain it's original condition better. For instance, at 250k on dino oil, that engine might be quite tired, making less power, putting out more emmissions and getting lower MPG. But the synthetic fed engine will still be making good power, getting good emissions tests, and acheiving good MPG. And the synthetic oil user could've done considerably less oil changes.
Not to mention the fact that heyjay mentioned the other day, about how in super cold climates you will have a hard time getting long engine life if you've been using conventional oil.
edit-I just realized I'm repeating myself here, since I've mentioned some of this earlier in the thread.

I totally agree here. My question is, where does a quality group III or blend fall in here? Is it somewhere in the middle or more towards the synthetic end of the spectrum?
Currently my 200,000 mile Civic on pure dino still maintains close to original accelaration. No signs of being tired yet and no engine repair ever. Mileage is still around 32-38 MPG same as always.
When it hits 250,000 miles I let you guys know if its tired.

My girlfriend has a Volvo 850 with the 2.4 5 cylinder. 182,000 on it. It holds oil about as well as a slotted spoon and has a rather audible bearing knock now, too.
She's had it since 161,000, it just recently started knocking a bit, but it's been leaking oil since she got it (which we didn't really realize until recently).
Honestly, I'm 100% disapointed with this vehicle, but that's a story for another time.
My mom's Astro van with a 4.3 liter had 210,000 on it when it was sold. Ran like a charm. Consumed a small amount of oil, about 3/4 of a quart every 3,000 miles, not too bad. And we still sold it for $2000, even though it was 11 years old! Bought new and changed oil regularly every 3000 miles with Castrol GTX 10-40 and a Fram filter...

This is so funny...
My girlfriend also has a Volvo 850 with the 2.4L I-5...has about 130,000 on the clock.
When she met me, car had about 100,000 on it and had spent its life on dealer-changed 5w/10w-30. Car ran O.K., but consumed a great deal of oil and visual inspection of top-end showed no accumulation of soft-sludge, but entire valvetrain area was covered in a dark, brown varnish.
I immediately drained the oil and filled it back up with Delo 400 15w-40 and a SuperTech filter. Car now runs smoother, engine is much cleaner, fuel economy is just as good, and oil consumption is next to nothing in comparison to what it was before...even in sub-freezing (15F) temperatures, the car started just fine with no "funny" noises.
DEFINITELY give a 15w-40 a try in this vehicle...think you'll be impressed.
And I have a 4.3L V-6 in my 1500 Chevy, but it has factory standard bad valve seals, so I'm running 15w-40 to reduce consumption in it 'till I get around to changing them...

My 1987 Volvo 240 with the venerable "red block" 4 cylinder B230F engine has about 484,000km on the odometer. Oil history is as follows:
1st year - oil changes ever 2500km with Castrol GTX 5W30 or 10W30 depending upon season with Volvo (Mann) filter
Year 2, 3, 4, 5 - oil changes every 5000km with Castol GTX and Volvo filters.
Years 6-10 Castol Syntec 5 or 10W30 every 7500km with Volvo filters
Years 10-15 Castrol Syntec 5W50 with Volvo filters. OCI at 10,000km. Consumption increasing to .75litres per 10,000km
Years 16 to present Mobil 1 Supersyn 10W30 with Volvo filters - we will see how it goes.....
(1km = ~.62 miles)

My 150,000 UOA is buried in my garage somewhere. I do have a scan of my 140,000 UOA available if anybody wants it.
Patman-
Good thread!
I have 206,000+ miles on a 97 F-150 Lariat that used nothing but Mobil 1 10W30 and a FL820S Ford filter. The 4.6L is still going strong. Oil/filter change every 5,000 miles.
