Mobil1 EP 5W-30 & M1 Oil Filter installed

Here’s hoping you at least get a UOA done at 10K miles to see how your vehicle is doing before blindly trusting a long drain oil like M1 EP series .

I don't understand your reference to 'blindly".
His vehicle is aged and DOHC engine is neither lspi-prone or TGDI / GDI. He should be fine using EP for 10k and may have been doing 10k OCIs in the past. We have numerous members here doing the same, without the oil analysis fanfare.

Robb's Signature says Mobil-1 ES 5w30. That should read ESP or EP. Perhaps he will respond again in this thread.
I'm not particularly fond of Robb's choice of K&N oil filters. They are full flow and don't trap well.

Just suggesting that unless you know how your specific engine does with your oil choice after you go north of 7,500 miles on an OCI - it may be a good idea to get a UOA to see how your engine is doing with your oil choice . Of course , you can do as you please - it’s your engine , oil and wallet.
 
Ì own a 2008 Corolla that drives 55 miles one way.i get 95%highway driving. Oil intervals come quickly, I use M1 EP oil and filter past 200k miles.
I just bought a 6 pack of Puralator BOSS filters and will try them out.
The K&N filter I put on the spare car cause I had it around.

That car and commute should handle 10k mile interval with ease with M1 EP. Might even go crazy and try longer, just mind the filter ratings.
 
Well, now comes the interval oil change on the 08 Corolla and I am using a different oil filter for first time ever. This car has only used Mobil1 EP oil filter and this time I'm using a Puralator BOSS
No big deal, right? I'm being silly but what if it blows when the BOSS filter spins on? HA HA!!! IM DOWN WITH 15 MORE HP!
