Oil and Filter Preferences

SCOTTLT79 · 03-19-2001, 08:19 PM

I do oil changes for work while I'm in school. The guys I work with couldn't come to a conclusion as to what was the better filter. Some said K&N and some said Mobil1. We all think that the Mobil 1 oil is the best though. Just a little curious around oil change time.
Thanks guys

I've used Mobil 10-30 (non-synthetic) along with a Motorcraft filter every 2000 miles since I bought my Mustang new, 11 years ago.
I've used a K&N filter since day one, too.
A stock-box model for nine years, then I switched to a cold-air induction kit (Moroso) with the K&N conical filter in '99.
Both have worked well and although synthetic oil is superior, I find that frequent changes with petroleum-based oil have almost the same result; long and reliable engine life.
My 'Stang has 109,000 miles and runs beautifully with no oil-related problems.
My opinion is that a K&N (any style) is superior to a paper filter and - regular or synthetic - frequent oil & filter changes pay off.

I run Castrol 20W50 with a motorcraft filter, and change every 2500mi. Been thinking of going to Syntec.

I use Mobil 1 synthetic oil and use the K&N oil filter.

Now talking about the Mobil 1 filter,that is also a good filter as like the K&N filter,it also uses synthetic material for the construction of the filter inside.

A lot of people have said that they like mobil 1. In a new engine, can I start it out on synthetic? I vaguely recall hearing something about running an engine on regular oil for a few thousand miles first, possibly to seat seals?

I'm certainly no expert but I was watching an automotive show on TNN a couple weeks ago and they had on of Castrol's engineers on. Castrol's guy said to break an engine in on regular oil befor swithching to Synthetic. I just fired up a new Motorsports 225hp 5.0 long block last week on Castrol 10w 30. On about the second oil change I'm going to Mobile 1 10w 30 synthetic

I have always used Valvoline oil in my cars and Fram oil filters. When I tore any angine apart that I ran valvoline, the lifter gally was clean with no deposits.
I think Castro would be my second choice.
I am sure synthetic oil is better but never used any.

I use 10-30 (usually Valvoline) non-synthetic oil and Motorcraft or Purolator filters in all my vehicles.

I use Valvoline 10w30 with a Motorcraft filter. Valvoline's been in all of my cars over the years. (and that's a lot of both

) I've never had a problem due to the oil. Any time I've taken an engine apart for performance upgrades or whatever reason, they've always been clean and without deposits or sludge inside. Back in the '70's with the older muscle cars we always used 20-50 racing oil, but it was still Valvoline. Also I always change oil & filter every 2000 miles.

Me personally i go with the recommended 10W30 weight Mobil organic oil (standard) and any filter besides Fram (i've heard that they filter so good that it lowers pressure enough to open up the bypass in the filter), but that's just me. I religiously change every 3000 (max). I've heard that as far as synthetic oil goes Mobil 1 is the best you can buy (that's why stickers under the hoods of corvettes say use only Mobil 1 and same with vipers if i'm not mistaken) but for street use there's no "bad" synthetic oil. i know that Pennzoil organic oil used to suck, but they changed from a wax based oil to what they have now (imagine lifting off your valve cover and seeing a yellowish wax coating...yuck).
