What makes one engine "hard" on an oil compared to another oil? For example, if you compared two identical peolple with identical driving habits, climates, etc., and the only difference was one had a pushrod SBC V8 and the other a Japenese DOHC 4 cyl. Which one would break down or use up the...

What oil properties make a difference in a valve timing control systems? According to the service manual for my car, "the intake camshaft pulley position is regulated by oil pressure, which is controlled by the valve timing control solenoid valve." The manufacturer recommends 10W-30 up to 20W-50...

I've been beating myself up lately over this subject and cannot come to any conclusions on my own. I've emailed K&N this same question and never got a response (get the feeling they don't really care about their customers) so I'm asking BITOG. I have a motorcycle that calls for a KN-303 oil...

The API Certification Mark "starburst" is designed to identify engine oils recommended for a specific application (such as gasoline service). An oil may be licensed to display the starburst only if the oil satisfies the most current requirements of the International Lubricant Standardization and...

Has anybody ever tried this stuff? I can find a few threads and some info about some Torco products, but I cannot find anything on their ATF. Here are the specs listed on their website. This will be going into a 2001 Pathfinder that calls for Nissan Matic D (of course) or DextronIII/Mercon. Only...

I have a 94 300zx with the VG30DE and showing 142k plus miles on it. It uses about 1qt every 1500 miles or so. I suspect most of the usage is actually leakage out of the rear main. Iam suspect of the rear main because I don't know if the pcv valves have ever been changed and they are a pretty...

I've been looking at the specs from different manufacturers for the filters on my vehicles and noticed that their are differences in the pressure relief valve. In fact, the filter for my 94 300zx does not even have a pressure relief valve, but the listed Amsoil filter states a 7-9 psi releif...

Anybody having problems going to www.motulusa.com? I've been trying and the site comes up with some other search site that wants to sell me flowers or something! What the heck is going on with Motul?

Since Amsoil dealers also sell Hastings filters, I was wondering if they as good or not as the amsoil filters. In particular I'm wondering about the Amsoil SDF13 and the Hastings LF240 for my Nissan 3.5. Right now I am using the Purolator PureOne PL14610 but have started to worry about not...

I've been using Syntech 5w-30 in my 2001 Pathfinder and now I'm starting to wonder about this GC I keep reading about on these forums. Does anybody have any opinions of one over the other? I'm also considering switching from 5w-30 to 10w-30 since we're now in full swing of summer her in FL. Any...

I just found out that my local Honda dealer quit selling Amsoil, which is a real bummer because it is super convienient and I really liked the way the Amsoil felt in the bike. They told me that they didn't stop selling it because of the product but because of the local Amsoil rep. So I guess if...
