Been going 5000 miles between oil changes (Regular oil) on every vehicle I have owned since the early 90's. Never had a single problem.. 95 nissan truck had well over 200k when I sold it. 99 toyota corolla (My beater) (Lol, and I beat the sh8t out of this car) as of today is at 213k and still runs very good with no engine problems or oil usage between changes. As far as my new Z car goes, I may just stick with the 3750 plan between oil changes, But have no plans on changing it any sooner. law Enforcement,Fire,Ems,Taxi's, they all go 5k and beyond between oil changes. It's very common to see these vehicles with 150k plus. Im not saying this plan is for you or anyone else, but this is what has worked for me for many years with very good results.
