Hi all,
New member to this site and hoping to get some advice. Proud owner (since 4.5 yrs ago and 87K miles) of 2008 Nissan Altima hybrid. Have been doing the oil changes regularly (5K) at the dealer but using optional conventional 5W30 oil. Recently, after coming upon few threads about benefits of synthetic for longevity and MPG, had dealer switch to Mobile 1 0W20 weight (recommended default) and just did another oil change myself and sent a WIX to get a UOA done. Results just arrived and I have been reading up on various variables and interpretations. The commends provided look generic (found identical for other miles/cars with Normal rating), so wanted to ask the experts.
I plan on keeping it few more years but need to replace struts (front & rear) and possibly do few maintenance things to keep it running tad longer. Before I throw the cash at it, wanted to see what the results are and if the engine is doing great (no leaks or high oil consumption that I can tell). What concerns me here is the Sodium level (being 45) but I am not sure if that's normal for the miles (148K). Also, any benchmarks for TBN (I assume 3.2) and Viscosity (8.5) after running 7,200 miles (granted its a hybrid and I tend to drive very lightly plus warm-up in the mild winter here in Northern CA, no frosts but does get into 30s in early mornings occasionally). Anyways, I am hoping you all have seen these so many times before and can point out anything that looks out of whack. Thanks and I am all ears!
