Internal traceability must refer to tracing the actual formulation (revision), as different plants can produce the same or a different formulation on a given manufacturing date. Plant 102 precedes it by "RN," clearly an acronym for "revision number."
No. The starter and battery are fine. The vehicle starts okay with a 5W oil.There is something wrong with either your starter or your battery if an oil with a 5W winter rating will not permit unaided starting at -10.
I amend posts several times before my English is to my satisfaction. Usually, two or three times, and sometimes that isn't enough. To that end, my original post you commented on stands as is. It wasn't changed whatsoever.I didn’t assume anything. What you posted was that the car needed to be plugged in a while. That’s a bit different then it starts but with somewhat of a strain (especially now that you’ve amended your post).
The other thing is it’s quite possible that the 30 grade is thinner than the 40 grade at that temperature. The influence of the winter rating for the 40 grade will not be apparent at that temperature.
That’s “packaged” Delvac - bulk volumes come from BMTI looked up Plant 102 in Paulsboro, New Jersey, which blends Delvac and TGMO. It also housed the ExxonMobil lubricant research and development center. However, they moved the R&D center to Clinton, New Jersey. The Paulsboro lubricant manufacturing and packaging plant remains open.
Here are pictures of the plant.
The plant had its recent troubles. It got sued in by New jersey in 2019 for polluting the environment with PCB, and it had a union dispute in 2020.
