I agree. Many keyboard naysayers on this site. I’ve been a member for over 20+ years and the ol saying about opinions is so true. Everyone’s got one. At least there are professional triboligists who can actually apply chemical science to this to make a better informed decision than what...
Good point and that’s my impression as well. In my applications, Valvoline Restore and Protect has been phenomenal in results on wear ppm/1k … reducing oil burn… cleaned up varnish internally… and quiet running engines and still at $29 per jug. All measurable data points. If I was Mobil, I...
With that said, which actually sounds like the talking points from Valvoline Restore and Protect team, what is your determining factors that would make you pick one or the other if you want very clean engine and will only go 5k-7k OCI’s? Price? Additive Pkg advantage? UOA comparisons...
Totally with you on this Knapp…. Too many folks on this website who stress their opinion vs thinking outside their comfort zone. If you have the data and the science that shows good results over the stereotypical’ Euro oils (the ones that got that car in the condition it’s in!)… then stick with...
Location is northern Indiana. Had a few weeks of below 0° for the day lows. I’m now back on 5w now
I’ve been that ‘backyard chemist’ for over 10 years. The data I have on my ‘08 Honda and other vehicles I’ve ‘mixed’ with has shown nothing but Excellent UOA all below 1.0 ppm / 1k miles. When...
Used oil analysis of Pennzoil Ultra Platinum. It’s a mix of 0w-20 and 0w-40.
0w-Winter mix but wanted something with a little more viscosity than straight 0w-20. CarQuest Extended Performance 20k Oil Filter. 70%-30% Highway miles. Just wanted a comparison to Valvoline Restore and Protect...
I do have access within my Ford Pass App that shows the service done on it because they took it to Ford dealerships in Michigan and Illinois for their service schedules. They had it going for basic oil service and filter changes on a 10,000 mile intervals. Only problem it’s had was engine...
You’re basically spot on about my viscosity choices. It’s essentially a long term experiment. Both my Honda Accord and Ford Escape call for 5w-20. My past used oil analysis seem to come out slightly better (marginally so) if I mix up a thick 20w oil relative to the viscosity range of 20w oil...
Gradually going to do that!!! What I haven’t mentioned as of yet is I’m now running Pennzoil Ultra Platinum with that CarQuest EP filter. 0w-20 and 0w-40 mix. I wanted 0w for the winter time. I was tempted to go with AMSOIL Signature Series 0w30 but chose Pennzoil Ultra Platinum instead...
Thanks. I was pleasantly surprised of the low wear rate. This next run I’m extending the oil change interval and running a CarQuest Extended Performance premium oil filter. Doing a bit of comparison with this filter and the MicroGard Select and where my particle count numbers shake out.
