My notes and service history say 85W-140 gear oil for my 1980 242 DL with 4 speed manual (M45) transmission.
I checked FAQs, which recommends 75W-90.
https://www.brickboard.com/FAQ/700-900/Driveline.htm#DifferentialOilChangeRecommendation
My Haynes and Bentley recommend GL-5 90 (my temps don't go below 15' F/C).
As a parallel, the Toyota front-wheel driver folks prefer GL-4 over GL-5 in non-limited slip differentials/transaxles.
Because my Volvo does NOT have a limited-slip differential, should I use GL-4, eg Red Line MT 75W-90, or am I okay with Mobil 1 75W-90?
How about Motul 300 75W-90?

Someone suggested to me Shell Spirax HD 80W-90, which he uses in his Volvo 240 differential. He claims it uniquely is SAE J2360 compliant, which I verified:
https://qclubricants.com/aeroshell/spirax_hd.htm
(it's not available on Amazon.com).
However, FAQs and other participants in this thread recommend 75W-90. Is SAE J2360 compliance of greater importance than a 5W heavier nature of the Shell Spirax?
Thanks

As Kitty says, use GL-5 in the diff. In a lightly-loaded rear end like the non-Turbo 240's, there's not much point in using a synthetic - especially if you don't see very cold temperatures. I'd say just shop for conventional 75W90 in a name brand like Castrol, Shell, Pennzoil, etc, in a GL-5 rating. That would probably be as good or better than the lube Volvo put in at the factory.
Make sure you can remove the filler plug before draining the diff! Some unhappy stories here in the past from folks who didn't.

Thanks.
How often do you recommend changing the rear differential fluid in a non-turbo?

Thanks.
I have Haynes and Bentley in hand.
I posed this question, because these manuals are old (eg Dexron ii for ATFs), less conservative than this bulletin board, and I value this bulletin board's members' recommendations.

yea a thinner lube may get better mpg...less rolling resistance

143k miles. It's been in storage and I'm planning to register/drive it soon.
I believe that the rear wheel bearings are sealed and can't be repacked (1980 Volvo 240 DL) per Bentley, but that's only for 1983-1993. Last week, I repacked the front.
I've never heard of NLGI-2 rated grease. What are the advantages? Is NLGI-2 different than EP2? The FAQs are silent on this issue. Bentley only says, "high quality wheel bearing grease." Haynes is too disorganized and doesn't have a listing in the index (typical and they frequently have the wrong page number).
I have a 96 Tercel FWD with a transaxle. The Toyota people recommended Red Line MT-90 75W-90 synthetic GL-4. I was using Mobil 1 GL-5. Now that I switched, it shifts like a dream.
By the way, I use Red Line MT-90 in my Volvo 240 DL transmission.

The Bentley manual, I guess, shows procedure to remove the rear axle half shafts after removing the hub works including the parking brake assembly.
If fitted with alloy wheels, and they show corrosion, making alloy wheel contact to the hub works (front and rear), the more noble ferrous alloys tend to coorde faster. Consider parking brake shoe replacement. Why I don't like alloy wheels in part. Particularly the 15" Virgos. Very heavy and soft are Virgos.
NLGI-2 is the viscosity. Than you have application rating as wheel bearing grease and temp range and the soap complex. I guess it is lithium in the Volvo wheel breaing grease tubes? EP2 grease may be too thin? I'm unsure.
Though I have yet to see or recall, the rear wheel bearing on rear wheel solid axle bearings should be inspected, cleansed, and repacked every 50k or so.
GL5 lube has twice the extreme pressure (EP) compounds to prevent shear over GL4. Volvo gear boxes (M46 as with your 240) for RWD have copper "yellow" alloys at the synchros.
GL5 gear lubes include sulfur compounds that cause yellow metal corrosion. Great for hypoid gear assemblies of RWD differentials.
Some FWD transaxles use a common sump while other may have seperate sumps in one transaxle, and so the manufacturer specs indicate what goes where between manual gear box and differential, yet all in one housing. In single sump FWD transaxles the manufacurer may spec GL5 lube, yet no yellow metals. Ferrous alloy synchros in there to well tolerate the sulfur EP additives. Why differential oil you use in your 240 differential (any Volvo RWD rear axle) uses GL6, though PV may have spec another type.
The BW35 used Ford "Type F". I'm unsure the BW55. Yet AW7x can use Dexron III (and maybe newer Dexron, though am unsure this GM Dexron spec.) You can research articles here.
I use AMSOIL Super Shift Racing Transmission Fluid SAE 10W in two gear boxes. They run cool and shift better than before in two gear boxes. The gear box lube Redline specs for Volvo M47 may be slightly too viscous. Hard too shift a bit when cold.

I looked it up in a 1976 owners manual. The BW55 uses type F -- even though it is more closely related to the AW70/71 than a BW35. The AW70/71 are essentially a BW55 with a planetary gearset for OD added to the front. - Dave

Thanks.
I looked at Amsoil's webpage, but they didn't specify compatibility. Is that compatible with Volvo AW7* transmissions? M46s? Rear differential?
Thanks

Manual Transmission Transmission
Unlike Redline, Amsoil does not provide recommendation for all things RWD Volvo. Damn them.
Read your owner manual for these specs. The 700-900 FAQ DOES include guidance for fluid spec in 700-900.
Ask you MUST ask again, the 1980 240 owner manual page in manual gearbox lube:
1980 VOLVO DL, GL and GT, pg. 57 Transmission oil
https://volvornt.harte-hanks.com/manuals/1980/1980_dl_gl_gt/80DLGLGT_03b.htm#pg57
An improvement is synthetic Ford "Type F" or (rare) "Type G".
I do mention, in the prior post you're responding to with confusion, in M47, I use, in two M47 gear boxes (1990 240 DL li'l red Wagon, 1992 240 GL Sedan):
Super Shift® Racing Transmission Fluid SAE 10W
https://www.amsoil.com/shop/by-product/transmission-fluid/automatic/super-shift-racing-transmission-fluid-sae-10w/?code=ARTQT-EA
Amsoil indicates compliance to Ford "Type F" spec as well as Allison C-4 transmission (usually used in Ford up to the 1980s).
Though you can contact Amsoil yourself. The Ford "Type F" spec will work well with the M46 and J and P type Laycock overdrive unit. All Volvo docs, including owner manual and factory green manual, spec Ford "Type F" for both M46 and M47 after around 1977 or so? I'm unsure.
Yet at issue, on M47, and maybe the later M46, is that Volvo used a very high quality synthetic in M47 and maybe (I'm unsure) later M46. The Ford "Type F" properties, so far as I know (do your own research), work great for the pressure and temps the OD operates when engaged. Though seals in the overdrive wear. Some will use Ford "Type G" (higher viscosity) with a worn over drive (or overdrive with failing seals).
Automatic Transmission?
Do you own a 1980 Volvo 200 with auto transmission? This forum contains innumerable threads on proper fluid for BWxx and AW7x as does the 700-900 FAQ. AW7x uses Dexron.
1980 VOLVO DL, GL and GT, pg. 58 Transmission oil
https://volvornt.harte-hanks.com/manuals/1980/1980_dl_gl_gt/80DLGLGT_03b.htm#pg58
Read up in the FAQ.
Redline for 1980 M46: https://www.redlineoil.com/mtl-75w80-gl-4-gear-oil
If your 1980 has BW55 as 1980 Auto may be, Ford "Type F".
As Dave Volvo From Heck tells you.
Power Steering Fluid:
1980 VOLVO DL, GL and GT, pg. 59 Rear axle, power steering, brake fluid
https://volvornt.harte-hanks.com/manuals/1980/1980_dl_gl_gt/80DLGLGT_03b.htm#pg59
Says ATF. That may be anything. ATF Ford "Type F" synthetic after a flush. Use drop in or line magnet or filter.
Do you read your owner manual? Though Haynes has us incorrectly fill our power steering pumps with Dexron III (I did this, and the rack leaked through the hydraulic seals in a year or less into the inner tie rod accordion style boots). Use Ford "Type F" on 200 and older models. Perhaps 700-series and up to 1995 940? With the ZF and TRW rack.
Differential:
1980 VOLVO DL, GL and GT, pg. 59 Rear axle, power steering, brake fluid
https://volvornt.harte-hanks.com/manuals/1980/1980_dl_gl_gt/80DLGLGT_03b.htm#pg59
API GL-5 (MIL-L-2105 B or C) Viscosity: SAE 90
GL-5 with sulfur EP additives apply. Yet milspec changes. See the Redline site, shoose your model options.
https://www.redlineoil.com/75w90-gl-5-gear-oil
Yet how many miles? And you are leaking differential fluid through the rear wheel bearings? Better fix that.
Wheel Bearing Grease for Front & Rear Wheel Bearings
Amsoil:
https://www.amsoil.com/shop/by-product/grease/synthetic-polymeric-truck-chassis-and-equipment-grease-nlgi-2/?code=GPTR2CR-EA#B
Lithium complex grease.
Though I used for front:
https://www.amsoil.com/shop/by-product/grease/synthetic-multi-purpose-grease-nlgi-2/?code=GLCCR-EA
With new rear seals. Not lithium complex, so wash out old grease. Or get the Volvo OEM wheel bearing grease tubes.
Though as you indicate, you're losing diff oil through the rear wheel hubs. Rather catastrophic. Pull the half shafts, get new authentic Timken or SKF race / bearing sets. Replace on both sides. SKF (or Timken) made the blue seals the factory pressed in. An auto machine shop should be able to remove and press on the new races and bearings and seals on the axle half shaft with no damage to the axle half shaft. You marely need a puller or press or slide hammer (sort of awful to use) to pull out the inner bearing and race on the axle tube. You may want to use a seal press to press in the new seals.
Does that answer your questions?
I have to find a new job. The current take of cGMP blows at the mess I'm in. So, off to apply. Maybe a job in Spokane. St. Louis is a sheet hole as is the region around it in this polluted, rancid, radioactive (Westlake Landfill in Bridgeton, MO) riparian zone.
cheers,
Earl Grey Tea Boyeeeeeee.
