Eight years ago I switched to synthetic oil in my 1995 Maxima SE. I have been buying Esso Extra XD3 0w30 full synthetic. I recently bought a 12 litre case of Mobil Delvac Elite 222 0w30, which Imperial Oil's technical department here in Canada assures me is the same oil as Esso Extra XD3 it is a synthetic oil as the label on the bottle states and not a synthetic blend as stated in error on the box.
Has anyone been using this oil? It has a TBN of 7.7. Six years ago I sent a UOA into Blacstone Labs. The sample was at 8,000 kms (5,000 miles). The TBN was 3.8 and Blackstone said I could extend the OCI next time.
I haven't sent them another sample. Yesterday's oil change was at 10,500 kms using a NAPA Gold oil filter. I suspect I could have extended the OCI further than that but questioned how much further to extend it on that filter. I suspect 12,000 kms (7,500) miles would not have been a problem.
Any comments on this oil and what filter you use would be appreciated.
Thanks
