Question about pennzoil ultra platinum

[mrjlube]

Will the Borate esters in Pennzoil ultra platinum be a bad thing for fords wet oil pump belt? Trying to decide if regular Pennzoil platinum without it would be best for the wet belt. Appreciate any info. There is so much miss information I want to use the best oil to protect that belt.

Can you explain your exact concern about the borate ester and the belt material? In a chemical sense I mean.

I'm not sure what borate esters has to do with wet oil pump belts.

Not only does pup have WSS M2C9-60/61/62-A1 meaning it shouldn't have an issue with wet belts but borate esters don't react with rubber. They could react with water contamination more so than oils without it and maybe that could harm wet belts more however borate esters can and most likely are stabilized to not form boric acid in a concerning amount in the first place. It's a non issue for the most part.

Have Pennzoil new API SQ hit the selves yet ?

Appreciate that explanation

A mechanic at a local shop was telling me esters can eat a wet belt and make it come apart. That's why I brought it to you guys. I've been using amsoil xl but tries some ultra platinum in my grand marquis and it gets great gas mileage and is so quiet. Cheaper than the xl also. Trying to decide if I should make the change permanently. You know how we like to obsess over oil . Thanks for the info guys. Hope you all have a great day!

It's a legit question and concern.

On their own esters could affect seals and rubber sure but there's ways to prevent that if an oil is fully and properly formulated. Its been discussed a while ago.

Do the higher percentage of esters and PAO's found in higher end oils shorten the life of internal plastic engine components, such as timing chain guides, plastic valve covers, oil pans, seals gaskets etc.?

I remember having a plastic funnel I used for drain oil that got brittle and cracked from contact with these oils.

Also, does the higher esters content attract moisture more so and should be avoided if the vehicle is short tripped or in a humid climate? and would the engine be better off with a cheaper oil changed more frequently?
