Mobil 1 Advanced Clean formulation change
- Thread starter tolian21
- Start date
I'm running it long term in one of my cars, but not for the cleaning. The PDS had some really compelling figures on it before the mystery base oil swap and I just picked up several from walmart on the cheap.
Just started the first OCI last month.
Yup. Effectively getting 5 quarts for $12 sounds pretty good to me. That's why I'll be using it for my next oil change in the fall.If you buy it for $26, and get $10 rebate and $4 WM
cash, its a good reason to run also
I found jugs of the new formula, i verified it with a change in the 4 digit revision number on the back of the jugs. It is still dexos 1 gen 3 on the label
How can you tell based off the numbers?
Also is the older formulation supposed to be better than the newer one?
Dexos gen3 was never dropped, it was a mistake in documents.
Formulation changed mid May as per SDS, but we dont know if they started using new formula before documents changed. I dont think rules are very strict on timing
Mobil has a date code on every bottle and at the end of it it usually says RN**** and in this case it was RN7165 and now the latest jugs on my walmart shelf are RN7223 IIRC i just did a quick peek waiting on a prescription to be filled. The revision number is unique to each product line and a change signals a formulation change. Ive got no idea what the number itself stands for or if its just a formulation number or what. Like EP is all the same RN, regular is to, EP HM, HM etc. only ESP has unique RNs for each viscosity so they truly are different formulas and not just different viscosities with the same formula. Interestingly enough is ESP x2 was 6288 for atleast 6 years and last year changed to 6353 and now the latest jugs are back to 6288, unsure what that signifies.
What's the date code on the new jugs?
I think it was 10126E which i understand to be plant 101 year 2026 month of may
