i have a 2005 pontiac gto 24000 miles , the manual calls for
75w-140 diff oil. i called friday to see if my pontiac dealer had the friction modifier 7098 to add to the fluid. he said that three months ago gm changed the fluid to 75w-90 and that the friction modifier was no longer avaible to purchase. he said the new oil came mixed with the friction modifier in the bottle.
i called a chevy dealer and have been told the same thing.
i don't know alot about oil so that is why i am here.
now the questions
why would they change the oil from 75w-140 to 75w-90 ?
and should i continue to use 75w-140 ?
can i purchase the friction modifier 7098 some where else ?
thanks for any help tim
