I know there probably would not be much of a difference between the three oils and I'm sure this has been asked before in different ways, but which of these oils would most likely give the best wear numbers without thinning too much. I can get these three oils at the same price so I was just wondering what everyons opinions are on these oils. I know GTX does not have the best cold weather properties, but have shown good UOA results regardless. All contain a decent additive package with Moly, so this makes it hard to decide which to use. Any opinions??

Not hard for me. I have been using Castrol products since they used castor bean oil in the racing formula. Used GTX in my TR3 since 1974 and in my Toyota since purchase in 1990 with no major problems. I do feel synthetic oil offers some improvement but have not been able to prove it yet.

I'm using all 3 right now. [Big Grin] Castrol 5W20 in my Escape, Pennzoil HM 5W30 in my "HM" van, and just put Chevron-made Havoline 10W30 in my Altima over the weekend.

I've been using GTX in my '87 Grand National since new and now 115K later running strong. Actually, DREW99GT is right on, take a pick, they're all the same as far as your engine is concern, anything else is just theory.

What are you basing that on? Pour point alone? ya know wear numbers do make a difference. GTX has done prety well in the wear category. --Matt [ April 10, 2003, 12:28 AM: Message edited by: mkosem ]

According to the VOA, Pennzoil Long Life has a nice dose of Moly and some pretty decent ZDDP numbers!!!

Chevron Supreme without a doubt. Super stuff and about .50 per quart cheaper. The savings will pay for a SuperTech oil filter [Big Grin]

My vote goes for Pennzoil higher viscosity 8.6 cSt at 100C versus 8.0 cSt at 100C for the chevron supreme plus it has a nice dose of moly.

I'd pick between the Pennzoil and the Chevron. All three are probably close but I'd give the nod to the Pennzoil & Chevron base oils being more shear stable and the latest Chevron samples have showed high borate additives ... all for $1.08 per quart. Like others here, there are a lot of little things I don't like about Castrol in general ... easily enough to tip the balance between these three more-than-competent contenders. --- Bror Jace
