Castrol GTX 5W-30 Conventional Motor Oil (1 Quart)

Part No. 06144 Warranty Details  
TriShield is a unique triple-action technology that attracts, captures and disperses particles that can build up in engines and causes sludge build-up. TriShield stops small particles from becoming big problems, and protects the car you rely on. This innovative technology uses a polymer that contains two chemical hooks that attract and capture both sludge and soot in a single molecule, helping to prevent particles from building up. With TriShield Technology, Castrol has improved the potency and protection that GTX provides.

Product Features:
  • Unique TriShield technology actively protects against particles that build up in car engines with the most advanced sludge-fighting ingredients
  • Castrol GTX uses premium, custom-made additives and is the most advanced conventional oil available
  • Maximum protection against viscosity and thermal breakdown
  • Extreme detergency action helps prevent deposits
  • Exceeds API Service SM, SL, SJ and SH; ILSAC GF-4/GF-3/GF-2 for API Certified Gasoline Engine Oils; meets Energy Conserving Standards; GM6094M
  • Exceeds demanding US high-shear and stay-in-grade requirements for viscosity breakdown protection

I switched from the oil in the yellow bottle that starts with the letter P and I tell you I think my truck is running better with this oil in it. It seem to reduce engine noise, feels more smooth. I know I had about 3-4k miles on the last oil change so dont know, either im seeing and hearing things or something changed.

I bought a used Honda Accord with 70K on it. I was initially running Motorcraft 5W-20 synthetic blend because I also had an F-150 that took the same oil. At 100K I pulled the valve cover to do a valve adjustment. Clean as a whistle inside. I had been noticing though that the engine used a small amount of oil, about 1/2 a quart every 1K. I found this is common for the 2.4 Honda engines and the easy fix is switch to 5W-30. This is the point I started using the Castrol GTX.

A little over 25K later I again removed the valve cover to install a new gasket set. I was shocked to see sludge deposits all over the inside of the valve cover. Some more research verified this oil is prone to coking. I will no longer use Castrol GTX. If you like it fine, but DO NOT let it go past 3K without a change. I don't do short trips or dirt roads and figured 5K changes were fine, as they were with the Motorcraft I used previously. Wrong. You have been warned.

        Comments about Castrol GTX 5W-30 Conventional Motor Oil (1 Quart):

        Anytime you can get quarts of name brand oil at less than $4 a piece, is a great buy in anyone's book. Ordered online & BOOM! Walk in, get oil, walk out. It just doesn't get any easier. Don't have search for what you're after, and only finding what you're after, after finding everything else you don't need. Online ordering is totally the way to go when buying auto parts, and with Advance, it just can not be done any easier, not to mention all the great discounts for being a repeat customer. I don't buy locally from anyone else.

                  The description says "•Extreme detergency action helps prevent deposits".
                  But the specification says
                  "Detergent or Non-Detergent: NON-DETERGENT"
