Great stuff
Best oil treatment for older vehicles to add some life for an older engine.
Good stuff
Good product and price
Love this stuff. Just seems to run a little better every time.
one of the best products ever made.
Finally realized buying single bottles from store wasnt smart. Although the case was delivered in rough shape, like it has been left in rain and than fried out, the contents inside were ok, no broken/leaking bottles.I will say I think these are old stock simply from labeling being different than what is on a bottle on store shelf right now, but not a huge deal .with multiple vehicles, just smarter to buy in bulk if case price allows .
Use in lawn mowers and older 80-90's cars. Adds zinc or ZDDP that older cars need. Can't hardly wear a mower motor out with this added to the oil. Have a 14 year old B &S motor that runs great still today. Would NOT use this formula on any newer cars. Can be hard on the catalytic converter in
OK for what I needed.
I’ve used STP for 50 + years it’s a great product, in cars , trucks & tractors.
My Family has used this stuff for as long as I can remember.If it's still made here and didn't change the formula I guess it's good.
Like to add this stuff old cars that sit around alot.
Good for your car or truck.
I always buy STP Oil Treatment for all of our vehicles and have done so for many years.This order was for 12 bottles but, for some reason, there were only11 in the box. Don't know why but that was what arrived. I contacted the seller and was issued a refund for the whole order, without a return being required. Don't know why, but that was a surprise. I still like STP and will order again, when we need it. I read the reviews and others had reviewed the same issue. I just don't know why they don't fix the issue so that others won't have any issues with their order.Good product, and fast shipping and fast response when contacted about the issue.Will buy again.
Great value here for a name band product that has proven itself over and over.
I have been using STP for 50 years and will keep doing so. I have never had an oil related engine failure. %0 years of driving, and owned over 50 cars. I HIGHLY recommend it!!!
Fast shipping. Good quality.
I use nothing else in my oil.
Dad put a pint in every oil change, and it seemed to keep those old cars running. On the other hand, he did change the oil about every 3-5 thousand miles. Cost more than $1.50 now, but in bulk is an ok buy. I put in the differential and (manual) transmission, too.
Only way to buy, by the case. Great value compared to individual bottles. One of the few oil treatments that contains ZDDP without being all about that additive. I run this additive in numerous engines in vehicles 30-45 years old to provide protection for the cam lobes and lifter bases. Never had any issues with a treatment at every oil change.
