Question 1

Do all Royal Purple Synthetic Oils contain Synerlec Additive ?

Accepted Answer

This hasn’t been updated for a while now and it should be. Just purchased 5qt Royal Purple 5-30w for my POS ATS. According to the website Royalpurple.com I believe almost all of their synthetics contain Synerlec. Their website is very informative about their products. Also helpful in making sure you get the correct oil for your vehicle. I will admit at this point in time it’s cheaper through my Amazon Prime. Retail stores seem to be about $40 currently 6/2020

Question 2

Is this a synthetic blend or full synthetic

Accepted Answer

Full and like real full not It's just as good as amsoil the only 2 oils I put in my car and I have a bmw 325i it requires full synthetic high performance oil, and lots of it so I highly recommend this product or amsoil.

Question 3

I live in a place that ranges between 50-100 degrees Fahrenheit, will this oil work for my  2011 f150?

Accepted Answer

It should no problem as long as Ford states that 5-30 is your recommended oil type. I have a 2014 Forester XT which has a 2.0L turbo engine. I've been using Royal Purple oil and filter since it's first oil change. This is amongst the RP oil I put in my 09 Challenger SRT-8 as well. NY weather ranges from 0-100 degrees and lots of elevation changes, stop and go traffic, rain, wind, and snow.

Question 4

I have used ac delco dexos oil previously.  how does royal purple compare?

Accepted Answer

I think I'd have to agree with Billy. I currently own a 2008 Subaru Impreza 2.5L A/T and although for whatever reason my does tend to burn oil a lot, I found myself questioning this oil. I literally had to add more oil to my car about 2 quarts of full synthetic oil (an unknown brand) which was another from another brand of oil instead of Royal Purple, according to my mechanic. I also found myself have to add more oil prior to this event with my mechanic and at the time of doing this on my own, I also noticed my oil is a bit dirty. I'm going to stick to my manufacturers (Subaru) brand oil it seemed to work best for me and use a K&N oil filter and call it a day.
