Does this stuff only benifit when it is in the oil, or does it seem to fix or stay in the system after the oil is changed? Want to try some but cant really justify that much money if I only get a short term benefit while it is in the system.
Hopefully that makes sense what I am asking. just trying to figure out if I will see and benefits after I change the oil and the rev x is drained out.
It does not stay in the system except for the ~4 quarts of residual oil in the injection system.
It's "effects" are long lasting. What effects? The cleaning. L
Sets say you use it for 6,000miles. Now your engine is clean and will stay clean for a long time depending how how often you change your oil.
Standard oil no more than 6,000miles, syn, no more than 7,500 miles.
While some will stay in the engine at oil change most will be drained along with the oil. I'm personally going to add the 8oz of Rev-X every other oil change along with the T6 synthetic.
I would add another 4oz every other oil change or so. Preventative maintenance!
I do not feel the same. Preventative maintenance is changing your oil with in the increments I posted a few lines above. I feel that 4oz or 8oz every other is wasteful of money. If you want to do it every 20,000miles, I would not argue against it.
I have gone 73,000miles with out having cold start issues. I have used syn since ~25,000miles (with a handful of ford 15w-40 from warranty work. I went 5,000miles every time.) and changed my oil every 6,500miles untill I got my bypass.
