Burla,

The one thing i did notice about the difference between the fram 10060 and the RP 20-820 is ( besides the obvious larger filter body itself, LOL) the OD & ID of the gasket is slightly larger on the 20-820. Didnt measure but just eye balling it... its around .0625” bigger diameter. So “centered up” when mounted....maybe about 1/32” bigger all the way around. Give or take.

Side not to all,

So if you are going to the bigger filter for the first time. Double and triple check the maiting surface on the oil filter location is clean. Because you may be slightly touching part of that machined surface that has never been touched before. Could have some stuck on dirt on it.

JMO

Thats a good point, I know the filter housing on mine has surface rust where the filter doesn't touch. I have both a small Mopar filter and the larger 20-820, I'll check out the mating surface on each when I get home from work tonight

Fram ultra. 10060
Royal Purple 20-820

Gasket OD: FU 2.76 av
RP 2.84 av

Gasket ID:FU 2.48av
RP 2.45av

Gasket Thickness: FU .14
RP. 195

Can OD - FU 3.00
RP 3.665

Can hight- FU 3.38
RP 3.86

Fram ultra: made in Canada
Royal Purple: made in USA.

These measurements were taken with my “General” calipers. They are just my perceived dimensions.

Checking for mistakes now LOL.

Question from a paranoid guy.

Will this dent affect anything? Its about .8” round.

69GWC · Dec 4, 2017

Changed my oil to RL at 6,000 miles and now have 11,000 miles so right at 5k on the oil.
So I checked to see what the trucks oil life monitor was rating the oils percentage at and it is right at 52% , so will see how its looking at 7 or 8k miles on it.
Just kinda wondering how accurate this percentage read outs going to be. Has anyone compared the trucks percentage of oil life to what Blackstone said they had left on there oils life. ?

Just wondered if I had some cheap generic oil if it would still be reading the same percentage ?
Thoughts.

Wonder if Corey (hemi) can put a caliper on the mopar filter gasket OD. That would be interesting to see how close they are.

I think this is pretty much what you’re looking for

Your no fun. ^^^^

LOL

And my hight measurment was with the gasket.

Hemi395 · Dec 4, 2017

I don't have a caliper but my crude method of measuring came up with basically the same results. The smaller filters gasket is slightly smaller than the 20-820. Good find U&A I'll be taking some 400 sand paper to the mounting surface in the spring when I change my oil again

What Blackstone is looking at is much different variables when determining TBN , interesting though that your OLM for your current oil fill idicates approx 960 miles per 10% of oil life , I'm running a 50/50 mix of RL 5W-30 & RL 10W-30 ...I'll try to remember tomorrow to see how many miles = 10% [emoji106][emoji106]

Yeah I was just wondering if blackstone said you could run that oil for X,*** amount of miles further what your trucks olm was saying the percentage was left on the oil, like if they were close to each other.
Just wondering how accurate the OLM really is and if cheap oil really effected the out come on it or if it was just reading hours and mileage.

The OLM is simply an algorithm. It computes the oil life percentage from a set of variables such as number of cold starts, Max oil temp, Max rpm, avg engine load, ambient temperature, etc.Also I think it's programed to go to 0% by 10000 miles but I'm not sure about that. IDK I've never been a fan of any OLM.

AFAIK it can't tell the difference between cheap conventional oil or Redline. It's the main reason I go by the mileage Blackstone recommends rather than the OLM.

Good post

69GWC · Dec 4, 2017

Thats what I thought, I have allways read that people go off the OLM for there oil changes and really this just seems to be a bad practice if you were to use a pour quality oil.

U&A · Dec 4, 2017

I have not reset mine for 2 OCI and when i drained and refilled it didnt change.

I don't know but this is just my thought with all these tattal tale computers is if you don't reset it the dealer could access the OLM and claim you're weren't keeping up with periodic oil changes and possibly deny engine warranty claims. I don't know if that is even possible but wouldn't put it past them.

They sure do... Don't you guys get monthly "Health Report" emails from them? This one is from when I experimented with a 12k OCI on Amsoil SS. They definitely know. I ain't skeered.

I've never got one of those, I just keep getting calls and emails from my dealer and salesman that they haven't seen me in awhile . Is that something you signed up for?

I think that report is for the 2016+ vehicles with uconnect. My wife's 2017 Grand Cherokee gets those monthly reports

Ramnewbie · Dec 5, 2017

Maybe that's it, I've never messed with the uconnect thing. To tell you the truth I don't even know if my 17 express has it.
