Late P80 power steering fluid - Not listed on parts sites? Topic is solved

[V50M66]

@MOVolvos "Swepco 306 15W40 and Swepco 714 20W transfluid" What combo would you recommend for a turbo P80 with 100K and a NA P80 with 180K?

Both should get 0W-40 (colder climates) or 5W-40 (warmer climates or aggressive driving) full synthetic that meets ACEA A3/B4 certification, usually labeled as Euro oil. Don’t run Liqui Moly - their 5W-40 burns more than others because it’s noticeably thinner for some reason. I run Total Quartz since I got it on clearance, but Castrol is the usual go to for these cars.

There’s nothing special about any transmission fluid for the P80 4 speed auto - Valvoline Dex/Merc is what I use, but any fluid that meets Dexron III specs will be just fine. There’s no reason to spend extra money on fancy stuff. The 5 speed is a totally different story, but this 4 speed doesn’t need anything special.

You should NEVER run 15W-40, conventional, or diesel oil in these cars, regardless of what Mr. Swepco rep over here tells you.

@Movolvos "where you dropped off the 00 S70 sub frame brace". Was this directed at me? When I bought my 2000 S70 GLT SE back in March of '22 the trans fluid looked like as you described, silvery thick coffee. I replaced it with Valvoline Dexron VI. Shifts ok but seems to jump into gear once in a while. The shifter is also harder to move than I would expect, at least compared to my '93 850. I drive it maybe once a week.

Dex VI isn’t the right fluid for these transmissions. It should have Dex III in it

Normally I wouldn't run 15W40 nor 20W50 during winter. I've only had one minor hick up with the worn 98 S70 T5 motor using Swepco 15W40 and this for many many years and year round in quite a few makes and models. I believe I'm currently running Rotella T6 15W40 in the following and will see how it fairs during winter.

I had purchased 6 gallons during a super sale last year. Just recently started keeping track again after years of low mileage use of the various vehicles, so sometimes only annual oil changes rather than 5K or 6 months.

I'm not a big boy but back in the early 2000's did know a few who transported their Porsche and Ferrai's for track days and have toured the Weissach facility besides training at Bob Bondurant. Swepco has been around for close to 100 years and is well known in heavy industry and racing so not a boutique oil and as for being a Rep . It's that good! United, US Coast Guard, UPS and Chevron are few that who use Swepco and use to be listed on Swepco's website till they were bought out a couple of years ago.

Pretty sure they still have tours of the Porsche facility. The speeds were so fast riding with the test drivers one of the guys in the group opt out as he couldn't stomach the forces and speed. I believe the tour may have included driving your own car on the track with one the test drivers in the passenger. Not in that realm of society so didn't pay much attention plus it's been years and the guys have grown out that stage in life and are driving normal cars.

Lastly, I only post if I have had first hand and sometimes lengthy experience with a product.

Yes, that's the first time I've ever seen fluid that bad and the transmission was still running. I used to own an 89 Mazda 323, same car but with trim rings on the steelies . The transfluid was literally silver when I got it. Change it out with some generic fluid and the car ran till the summer and one day it just went south on the way home and was really, really limping on the freeway. It's a good thing it can take up to 1.5 hours for 25 miles to get home from work in CA.

I remember getting off the freeway and nursing that thing from light to light till it made it home. Swepco with 714 20W and added a Hayden transmission cooler and it was literally flying though it did have a slight bump shift if you WOT too many times. That was in my younger days of course and the 323 was a fun little car with wider tires.
.
I installed this cooler with the Swepco and it's in the 03 Odyssey also with 249K on the OE transmission. Fluid still new after about 5 years on the Havoline Multi-Vehicle Synthetic Transfluid.

Jesus this thread is going off the rails. There’s a reason nobody has heard of or uses Swepco. You’re using the wrong oil if you aren’t using A3/B4 rated 5W-30, 0W-40, or 5W-40 Just because “it’s fine now” doesn’t mean it will continue to be fine. Why use the wrong stuff on purpose? It’s flat out stupid and you will cause issues down the road.

Aren’t you also the guy that hot glued an engine mount back together? LOL

Dex VI isn’t the right fluid for these transmissions. It should have Dex III in it

Anybody else? III or VI?

Yes, expect most people haven't heard of it nor have done the research. Unless you are in the the European, Porsche, Ferrai or high end engine builder community you won't hear about Swepco. As for the hot glue, if the melting point was higher it would have been an exceptional and potentially permanent quick fix.

There are three kinds of Volvo owners (In, Out or In and Out of the box as needed). The dealer by the book or hey we found Volvos poor designs we can do better and sometime better than the mechanics or somewhere in between.

These Volvo guys have heard of Swepco.

The article below states the industry understanding of ZDDP on the CAT. Due to the Tribofilm created by ZDDP and the other synergistic additive the Tribofilm offsets the normal blowby of an engine so less emissions. Never had a CAT issue using Swepco.

"Many Porsche repair shops have acknowledged that these newest SM and CJ-4 motor oils are not sufficient for protecting any Porsche engine. With longevity and the protection of vital engine components in mind, many shops are recommending the addition of GM's EOS Engine Oil Supplement at every oil change. Shops that used to run M1 in their race cars have either switched to Mobil's synthetic motorcycle oils or have resorted to using premium dino oills, such as Swepco 306 15w40 or Brad Penn Racing 20w50 oils, for their higher levels of protection. For most owners, the reduction in longevity of a catalytic convertor is a small price to pay considering the many thousands of dollars it costs to properly rebuild a Porsche engine."
