The first oil I ever used was Castrol GTX 20W-50, back in the day. With time I moved on to bigger and better things, Penrite oils, full synthetic oils, etc.
Being a belts and braces sort of guy I have been using a lot of full synthetics (Castrol Edge, Shell Helix Ultra, Valvoline SynPower) with name brand semi-synthetics as my base level oil for some applications.
Anyway last week I went back to basics and put some Castrol GTX in my car. The owners manual specs a 15W-40 A3/B3, so that is what I used, GTX 15W-40 API SN ACEA A3/B3. This is the first time I have used GTX for an oil change in about 15 years.
Yesterday, I went for 8 hour drive through the mountains with my son, and the car was running smooth and well. Given the modern specs, this is not the GTX of long ago, but the modern inheritor of the old crown, at an excellent price point.
Lots of talk about PAO and GTL, but going back to GTX was like bumping into an old friend who is happy and doing well.
Is anybody else out there using old school GTX and enjoying it ?
