After reading this forum it seems conventional oil is gone and i haven't been able to find any at the local stores. How will the synthetic blend affect older high mileage vehicles?
I have two older high mileage vehicles that do not leak or use any oil. One is a 1996 Tacoma with 210,000 miles on it and the other a 2011 corolla with 190,000 miles that gets driven 20,000 + miles a year now.
These two vehicles have never seen synthetic oil. The corolla book says to use 0w-20 or 5w-20. I've been using pennzoil 5w20 conventional all it's life. The tacoma i've always used 10w-30 conventional.
Should i use full or synthetic blend in these vehicles?
Some say it can cause a leak others say it will be fine. I did look at the specs sheets for pennzoil 5w20 conventional vs 5w-20 synthetic blend and to me i don't see much of a difference.
In my newer vehicles i have used full synthetic since day one with zero issues but they where new without a lot of miles.
I've never used the so called high mileage oil as i have no leaks and never have to add oil between changes.
Thanks for the help!
