Replying to: harrisblack (Jun 26, 2008 5:06 pm) I have been using full synthetic for years and it is worth the extra money. There are many brands and as many arguments about who has the best. Regardless of which one you pick, Stick to it, don't change brands after you start. The 3,000 mile change rule should always apply. It will pay big dividends ten years down the road. Regarding oil filters, again draw a circle on the ground, take every brand and throw them up in the air, whichever lands in the circle use it. Is one better than another, (thought) is it worth the worry? Change every 3,000 with a new filter and the motor will stay clean and your rod and crank bearings will thank you for it.

In the December 2008 issue of Road and Track, on page 73, there was an ad by Valvoline. It stated that there Synpower full synthetic oil is 4 times better that Mobil 1. Any comments? Replies to this message: okko1 (Dec 07, 2008 7:07 am)

Replying to: rweldon (Oct 07, 2008 7:50 am) I disagree with your assumption that all oil filters will perform equally.   The dirt holding capacity may not be much of a factor, if you are on a 3000 mile drain interval, but the quality of construction, the performance of the anti-drainback valve, and the amount of time the filter is in the by-pass mode (like on cold starts), are not necessarily going to be the same across the brands.   Tom

I seen the ad in other media. Walmart has it for $19.00 for a 5 qt jug, which is cheaper than Mobil 1. Replies to this message: okko1 (Dec 09, 2008 3:43 pm)

Replying to: harrisblack (Dec 09, 2008 11:22 am) the maintenace and repair forum has a lot of info on oil quaulity that is worth reading. cost is not always a good measure of quaulity. mobil 1 is a proven performer. check out the other forum if you haven't yet it is way over my head but still has a lot of good info.
