What is your favorite motor oil?

A guy who was a mechanic and raced cars told me that the Kendall motor oil in the eastern USA was much better than the Kendall in the western USA. I heard that same story different places, and since I live in the western USA, I never used Kendall.

Kendall in the east though, was supposed to be really good.
 
Mystic,

How could they be different? Don't they probably have only one blending facility (in Bradford PA)? Also, and maybe this is the answer to my question above, isn't Kendall a Conoco/Phillips company now?
 
my fav oil right now is the German Castrol Syntec 0w-30, followed by Kendall Full-Syn GT-1 5w-40 (great oil for less than $4/qt! for me at least!

) and lastly Mobil 1 0w-40. If i couldnt get the german syntec then id go for kendall but, i would not have any probs with using M! 0w-40 if it was unavailable! In fact i used it for about 15K miles in my 02' Mazda Protege5 2L engine.

although its now been in the shop on & off for almost a month now w/ tranny probs. clutch & flywheel replaced @ 13K miles & again at 26K miles. Now, the whole 3rd gear assembly (includ' synchro) is new, as well as pretty much the rest of the tranny as well. pilot bearing, etc... This Mazda IS a piece of CRAP! Sorry...but i really dont think MAzda knows what theyre doing when it comes to trannies! OR whomever makes them for them!
 
I think they used to have different blending facilities in the eastern USA and western USA.

There have been so many oil company mergers and 'hostile?' 'friendly?' takeovers that I can't keep up with it all. Calvin, who used to use Kendall Oil, said that Kendall had been sold, but he did not go into details. Shell recently 'bought' or merged with or took over Pennzoil/Quaker State.

There was a guy who went by the user name of Johnny who used to come to this site a lot. He worked for Pennzoil-Quaker State. I don't think I have seen any posts from him in a while.
 
Johnny's probably very busy out selling Pennzoil! He hasn't posted here since June 24th, but he'll be back. Ya just can't stay away from this place for too long without going into withdrawl!

Went to Kendall website and there it was....

I like Mobil 1 for availability price and performance. I think Amsoil would have been my pick if Mobil was still using Trisynthetic. They all make some great and not so great oils in different viscosities.

Kendall pulled out of Bradford. From 1995-2001, I lived in Warren, PA, about 30 miles from the blending facility they used to operate in Bradford. I think they stopped producing there when Conoco bought them.
 
Amsoil 10-40 or castrol syn 10-40 in my ford truck (215K original everything until I finish the 331), amsoil 15-40 marine oil in my boats ONLY

Mobil1 GL5 75-90 in my lower units.

wolfshead mercon/dex3 in my auto trannies

M1 5-30 in the 98 olds

m1 5-30 in the 93 escort (1 change a year - grannys car)

walmart 10-30 in my 88 chevy truck (230K - not original) and 85 wagon (182K original motor) 5-30 or 10-30 in the 91 s blazer (185K original motor for 1-2 more weeks as soon as I finish that motor then likely 10-30 syn)

M1 10-30 and 15-50 mix (50/50)in the atvs

Golden spectro 10-40 syn in the V65 ONLY

walmart 30 in the mowers and garden tractor

delo or rotella 15-40 in the diesel tractors

walmart brand meeting UDT and massey MP fluid for the hydraulics

Id hazard those are my 'favorites' as each manu/grade is selected for performance and price (for example, the honda V45/65's REQUIRE that oil to save the cams, nothing else comes close)

I stock walmart brand in 5,10-30 and sometimes 10-40 and wolfshead if I can get it. I prefer not to do oil changes in my shop, but if I do, thats what they get unless they spec syn oil. I rebuild a lot of motors and have had 0 comebacks (proving you can do stuff right, I just dont charge enuf)

Do not like QS and pennzoil syn oils - caused too much valvetrain noise on my ford. wont use mobil delvac - too many horror stories from OTR drivers but I am gonna switch to straight 30 in the massey next change - probly use pennzoil 30HD.

have nothing against the other brands, but they dont offer anything over the wolfs head and walmart brands, and cost more (walmart oil is QS anyways)

I also dont beleive all the amsoil hype. however, 10-40 in that truck (since birth) have kept the valves quiet. now that Im on the twilight of that motor with a firebreathing 331 on the stand (at least I hope it breathes fire - we shall see) Im using the castrol as it gives the next best performance. as for the boat, last time I looked, only unocal made a marine oil similar and who knows where to get it east coast...I change once a year and use a massive gm filter for an 8qt sump...im not switching unless I have good reason too.

and u didnt ask, but for greases I use whatever I can get cheap in 13oz tubes for the tractor zerks and mower decks (1 tube does both tractors once), wolfshead red for auto suspension crap, pennzoil syn marine for all wheel bearings and lubriplate syn in the big tub for when you have to get messy.

wd40, crc 6-66 or 5-56, liquid wench and pb blaster are my sprays

if I need other lubs, I get whomever is decent priced and good quality - usually mobil, pennz or QS
 
Over the years I have only used three brands of oil and would trust any of the three. Pennzoil, Mobil 1, and Schaeffer's Series 7000.
Pennzoil 5w30 and 10w30
Mobil 1 10w30
Schaeffer's 7000 5w30 and 10w30

Filters I've tried:
AC Delco both Delphi and Champion Labs, PureOne, Purolator Premium Plus, K&N, Mobil 1, Wix, Napa gold(wix), Carquest premium(wix), Hastings, Champ, Super Tech, but never ever a Fram.

The Schaeffer's with either a Wix or Hasting's filter seems to be a great combination for me.
3-5K Oil changes for under 20 dollars is alright with me.
 
re: kendall, QS, pennz, wolfshead...

all of them used PA grade crude and were at one time based in pa.

Pennz-qs merged, own wolfshead and moved to tejas (the old refineries make specialty stuff and wax now) conoco got kendall and the refinery is now 'bradford penn'* (more on that later)

I still know that wolfshead uses pa grade crude, not sure if it actually COMES from pa anymore - we still have wells, they are still pumping, its going somewhere

* - bradford penn makes some decent motor oils used by truckers, machines and RR's. they are probly the only east coast source for straight 0, 5, 10, 20 etc oils up to 60, with or without detergents. they also make the gasoline sheetz stores use exclusively thru a deal with CLI hauling. so whenever sheetz raises prices to match others...I get pissed. sheetz does NOT have to compete on the open market for product....there is no reason for those increases.
 
QuadDriver, what kind of horror stories did you hear about Delvac from OTR drivers?

I'm in exactly the same boat. If German Syntec works out for my engine, I'll stick with it. If not its back to M1.

I like Bobzoil for my mowers and similar tools.

lower oil pressure, scored cylinders, ash in the heads, higher oil temps. duuno how scientific they guys who complain are being but everyone seems to feel rotella and delo are saviours of the planet.
 
Valvoline 10w-30 in summer and 5w-30 in winter with napa gold filters for my 02 dodge ram 1500.

wife gets Valvoline 5w-30 and Napa Golds year around in her 03 Hyundai Sonata LX V6.

we use 3k mile changes due to the fact that 98% of all our travleing is under 6 miles round trip to work and back. our motors in this small town rarely get fully warmed up. And there ISN'T a round about way to work either so dont suggest it...

I find that really interesting, because some guys at this web site say that Delvac is great, and should even be used in cars. How many drivers did you talk to? If it is a lot of drivers, then there is a problem here. I always believed in listening to what people in the field say. You could have what appears to be a perfect motor oil, but if the truck drivers using that motor oil are complaining, then somebody needs to take a look at that.

It is the results in the field that actually count-the real world is what counts. Now sometimes people in the field can develop the wrong perceptions, but if they are complaining, somebody needs to take a look.

well I only typically talk to a couple, but of those, 2 are immediate family OO's and one is a friend company driver and they do their share of talking to others.

I have noticed what you speak of here, a lot of people rave about products that dont do well in the world, and a lot of people are down on products that have perfect real world results. Shows how adept marketers are anymore huh?
