Don't I wish. My neighbors are junky.
 
I will have a 1 year, 8,000ish, UOA of RP 5w-20 with an RP filter from my 2006 Mazda3 2.3 posted on here in mid August. I have high hopes for this oil and filter.

The RP UOAs usually look really good. Looking forward to it.
 
Here's a VOA/7.5K UOA of RP 5W20 done at the same time from the same batch of oil, at the same lab last year. It still had a 10 TBN at 7.5K! And it was still well into high grade 20 category. No complaints on this oil from me!!

I'm impressed that the TBN is still 10 after 7500 miles AND 14.5 months. It could have gone 15k and 29 months.

I also get stellar results with RP 5w20 and my Mazda6i. If I could still get it at the price I used to, I'd only run it.
 
It's a very balanced POA...excellent additive package.

I have a WalMart that has RP in 10W-30/5W-30 and 5W-20.

The 10W-30 runs so very well in my 20 HP Briggs Tractor V-Twin...I am totally sold.

I am gonna try the 5W-20 as well.

My feeling is that if the oil dosen't shear down...you will be in great shape...has a high TBN...you can extend with confidence...moly and ZDDP are proven...this is a balanced oil...and if I am going synthetic...I am old school and prefer PAO's.
 
Too much abrasive detergent and not enough ZDDP. Looks more like a LOW SAP light duty diesel oil add pack. I dont like the balance. IDK what this detergent fetish is around here
