Switching to Synthetic

Been doing some searching and it seems that switching to synthetic has its benefits which may exceed its cost but are there any precautions or a procedure to follow when switching to synthetic the first time? Are you just draining it real well and filling it until the next scheduled oil change?

No special procedure. Just drain and refill as usual.

Yup, that's really the only way to do it. The 3-4qts left in the HPOP resivor can't be drained without some serious disassembly.

I changed to synthetic a few days ago. Make sure if you haven't changed it before, you have a stock filter setup (stock cap and seperate filter) before you drain the oil, especially if it's your only vehicle! I bought the stock filter, drained the oil, then found out that I needed a stock oil cap. Had to dig my Spyder trike out of mothballs to get to the dealer for a new cap.

I put in 13.5 quarts and it brought it up 3/4 way on the dipstick. I used Rotella T6 5W40. It was 21 bucks a gallon,filter was i think 18, both available at MallWart.

I use the factory-specified synthetic BLEND (I think). Where did you read that paying the premium for all synthetic can save you money, and how? I've never been convinced it makes much difference, but I'm open to changing my mind. My friend and I got a couple quarts of synthetic oil recently as a promotional product giveaway at an LA car show. I gave mine to him, but he would have had to buy more to use it and never got around to it.

No money saved from oil changes but from preventing repairs.

Much like the question about when or if to plug in when its cold and spend the extra couple bucks.... I take my trucks advice on the matter. When I use T6 and I plug in when its cold my truck lets me know how much it loves it by not barking when it starts up.....

Running synthetic will not guarantee against repairs. It may help a little with mileage but that's about it in my opinion. No matter what oil you use the 5000 mile change interval is what's important.

So the synthetic does not help prevent injector failure or remove the build up of deposits from regular oil? Nothing is full proof as far as preventing any mechanical device from failing but longevity between failures is the goal isn't it?

Yes it helps the injectors especialy when cold the synthetic oil not as thick so the injector doesnt have to work as hard to turn it off and on {That sppol valve in the injector has to shuttle back and forth]

When I changed to synthetic I just done the oil cooler so I pretty well had most of the oil out

Even if you still have some Dyno oil left in there not no big deal

I wasn't worried about getting all the old oil out. That will work itself out with enough changes. Just want to make sure the benefits of switching are worth the cost.

My suggestion to you waterboy, is to try one fill with a synthetic 5W40. See if you don't hear the difference in how your engine starts and runs on a cold Michigan morning. If you don't think it is any better, then you can switch back next time.

I can't say it will save you any repairs. I'm looking at a heavy bill to replace a bank of injectors right now, and I've been running synthetic for about 40k miles. But my engine really loves the synthetic every winter.
