You are splitting hairs over your decision. Supertech would be fine too.I was planning on ordering the Red Line 75w-90 GL-5 gear oil for my 2011 328xi BMW. But the Valvoline 75w-90 full synthetic seems to be really good on paper. It seems like everyone uses Red Line in their BMW differentials, so I’ll probably use it
Yeah, I know. It’s just that the Valvoline has a lower pour point, higher viscosity index, and it’s cheaper and available locally.You are splitting hairs over your decision. Supertech would be fine too.
The Valvoline doesn’t specifically state a recommendation for the specification that I need.Valvoline is available in the easy pour packs, similar to amsoil. That combined with price and ease of purchase at Walmart make it a buy for me.
Then buy the saf-xo from the dealer. Red Line gear oil isn’t special, except for the price.The Valvoline doesn’t specifically state a recommendation for the specification that I need.

They’re not even confident to recommend their product for my differentialThis stuff is better than Redline and cheaper. Just pay the $5. preferred customer fee and it's 25% off.

HuhMaybe you’ll change your mind and fill with Valvoline. Summer is a long time for a guy like you.
I didn’t hear about anyone using Valvoline in BMW differential, so I just played it saf with Redline. How hard is it to fill the front differential?Can't go wrong with either one. I have Redline 75w90 in my E90's differential right now, but did a driveline service on a friend's 2006 325xi this weekend using the Valvoline 75w90 synthetic he supplied. The easy-fill bags made the job 100x easier with zero mess. I was amazed how much easier it was and will likely be using Valvoline in the future for differentials just for that reason.
Redline is always a safe bet.I didn’t hear about anyone using Valvoline in BMW differential, so I just played it saf with Redline. How hard is it to fill the front differential?
Thanks. Did your friend‘s 3 series have the metal skid plate? I was looking online last nigh, and I was real puzzled. Do you know what size the bolts are?Redline is always a safe bet.
It's not too bad, but I highly recommend one of those fluid pumps, as it is next to impossible to get a bottle in there. The good news is that unlike the rear diff, the front has a drain plug. Just remove the metal skid plate (4 bolts) in the front/center of the car, and you can see the drain plug. The fill plug is on the driver side of the differential.
I'd invest in one of these if you don't have one, works great for the diffs:
Yup, metal skid plate right in the center under the oil pan. It had 4 bolts I believe they were 15mm or 16mm.Thanks. Did your friend‘s 3 series have the metal skid plate? I was looking online last nigh, and I was real puzzled. Do you know what size the bolts are?
