How does it matter where the oil formulations are being developed?
Very Impressed with Castrol High Mileage

Maybe since BP bought them they don't have them anymore, but on the old Castrol US web site (pre BP) they listed at least two blending facilities in the US. I can't remember where they were, though.
And I could be wrong about R&D still being located in the US, too. But whether or not the Wayne NJ offices actually have engineering staff who develop the North American oils is largely immaterial, IMO. Whether the formulas are developed in Europe or the US they are obviously good oils.
From my conversations with various engineers at Chevron, High Mileage oils contain 12-15% more detergents than regular oils. A look at data sheets shows that they are also thicker(at least this is true for Chevron/Havoline and Castrol; I haven't looked at others). I've also heard from those would seem to know, that they contain some synthetic base oil as well.
I have 6 quarts of Castrol High Mileage ready to go into the 1996 Ford Contour SE with 125,350 miles at the next oil change.
I hope it'll stop or at least slow down the oil leak that's leaving a couple of drops on my driveway every time I park it for the night.
If it does, I'll start using it on the 1988 Mustang GT with 178,200 miles, which is also leaking a little bit (but not as much as the Contour) from what looks like it's the rear main seal.
I auto-RX'd both of them and the leaks actually stopped on the Contour and then came back a couple of oil changes after the Auto-RX treatment. (I really didn't notice any difference with the leaks on the Mustang).
I picked the Castrol High Mileage because it was about the only thing Wal-Mart had besides Valvoline MaxLife. Looks like I picked a good product.

Is it your car that he's running at the strip??? NO. It's his. Do some of you feel so superior that you have to bust some guys jewels on an internet message board about what kinda car he ran at the strip? Believe me, I've seen A LOT worse at the drag strip.
I am very encouraged. I am trying to reduce the 1qt/2k miles consumption in my otherwise very clean and leak-free 99 Civic motor with 132k miles. I have a 5qt jug of 10w30 sitting in the garage right now. Not sure I want to put it in just yet, getting too cold for this thick 30w. Maybe next spring.
Can more people tell us their experience reducing oil consumption (not leaks)? Can someone please do a VOA as well? Thanks.

Does Stinky Peterson still do free VOA samples for for the site? If so, I would be happy to send him a VOA of both the 5w30 and 10w30 SM Castrol High Mileage. I was going to use him for the next UOA, which should be in a week. At that time I could send all samples to him.
In reading/searching, it appears that Castrol High Mileage is group II plus group V, with suggested good cold properties. Does this sound correct? Again, I am not certain, so more info is good.
Regarding your Civic: We are in Minnesota, and our vehicles have started very well with the HM 5w30. I understand in Canada the temps may be harsher, but it should be ok. Good luck!

Unfortunately, Stink Peterson was killed in a tragic accident a few months ago.
Oh no, I am so sorry. Please accept my condolences.
Wow, all these leakers. I guess I'm very fortunate. For the first time in my live, I have a car that doesn't leak a single drop. I have an 88 IROC Camaro with the 5.0L V8, and 160k on the clock. It burns a little between changes, but no leaks at all. The oil I use? Mobil 1 Truck and SUV!
The more I read on those HDEOs the better I like them. Looks like all those truckers were right after all.....
ARX/LC20 are about the best products you can use to help free up those ring packs and reduce consumption.... after things have been cleaning for awhile, take it out and drive the living crap out of it... get the RPMs up to the red and then let-off, leaving it in that gear, to engine-brake back down the the rpms a few times... call it a re-break-in.
Most consumption in "younger" engines is due to ring-pack contamination. I would call a Honda under 150k young.
Yes, my SOHC VTEC motor is very young now @ 133k miles
I've already used AutoRX around 117k with these results:
Compression ~1k miles into AutoRX Clean#1:
170-160-140-160 Esso XD3 15w40 HDEO used
Compression ~1k miles into AutoRX Rinse#1:
170-160-160-160 AutoRX and/or XD3 doing something!
Compression @ Start of AutoRX Clean#2:
170-160-160-160 No change
Compression @ Start of AutoRX Rinse#2:
170-160-160-160 No change
Unfortunately, consumption stayed the same 1qt/2-3k miles, with MANY oils I've tried: Mobil 1 5w/10w-30, Esso XD3 15w40 HDEO, AMSOIL ATM 10w30, Havoline conventional 10w30, Maxlife Syn 10w30. In my garage sits these fine oils: Havoline Synthetic 10w30, Valvoline SynPower 10w30, SuperTech Synthetic 10W30, TropArtic Synthetic Blend 10W30, Meijer High-Mileage (Citgo UltraLife) 10W30, Castrol GTX HM 10W30.
Fortunately, my engine remains clean to this day, see 131.5k mile pictures here:
Valvetrain
Valve Cover
Did a MolaSoak around 125k with LC20.
And as of 132.6k miles, my compression went up:
170-165-160-170
I guess all these short OCI (3k) scouring more carbon away. I started using LC/FP @ 132.7k and we'll see what that'll do. At the very least should clean the bit of varnish on my valve cover
I drive the crap out of my car indeed, many shifts up to 7,200rpm cutoff everyday. In fact I autocrossed this car 2-3 years ago but had no oil consumption back then. It just started for no reason around 80k miles. But I will intentionally try the hi-rev decel you described so that vacuum can do its thing on the rings with the next fresh oil and dose of LC.
I am so encouraged to try out the Castrol High Mileage that I may just go get me a Jug of 5w30 from big bad blue.

My Mazda V6 @ 280K km's is now getting the high-mileage treatment. Just changed the spark plugs yesterday and, wow the DIFFERENCE!!!
So yesterday I bought 5L Jug of Pennzoil High Mileage Vehicle (smells sweet, soo good!!) and later on I found a jug of Castrol High Mileage (does not smell as sweet
) so Now I've got a lots of high Mileage Oil to try and run through! This should be good
How about some VOAs?
Glad y'all have been so impressed with Castrol High Mileage. Just swapped in some 20W-40 into the '95 4Runner with a 3.0 V6 with 232,000 miles. It's been leaking from the rear main seal occasionally and I really don't want to fork out $400 to swap the seal out. Did the Auto RX treatment about a year ago and it really seemed to clean the engine out and the leak stopped for a while. Valvoline Max-Life didn't seem to make any difference. So we'll see how the Castrol does.
The leak was never there when I used Castrol Syntec, and appeared sometime after I switched to Mobil 1. Just an observation.
