I'm ready to change the oil on my 1990 Mustang GT. I just had a Vortech S-Trim installed not too long ago. What's the best Synthetic oil to use. I live in South Texas & it is always HOT over here.
You need something stout with a higher HTHS. Red Line or Amsoil (ACD) would be what I would drop in. By the way that is a nice ride and sure pulls like a screamer on that dyno! Very good job at plumbing everything in too- engine compartment looks mighty clean
does the mustang leak any oil due to boost? back in the day I did alot of work on those cars and none of them could keep oil in the pan, many reasons why, now Im sure there is a few fixes for this, I like the gapless rings for the pistons, hard to get guys to pay for it on top of all the other little expensive things a mustang needs to make its owner happy for a period of time
I would just buy a jug of 10w30 Mobil 1 from Walmart.
I had a 5.0 Mustang (stock heads and cam) running high 12's with just bolt ons and 3.55 gears.
What else does your engine have besides the Vortech ?
I was always a notchback fan, either way I'm sure he has a sweetride
Notchbacks are a hard item to find, we just searched and finally found one, a blue AOD car with 80,000 miles and all original steel on all 4 corners, got it for $3900 with a T-5 in the trunk, I took apart the T-5 and it was in good shape except for needing a syncro kit.
We looked for 4 months for a good car, alot had rust, hidded crashes, more rust geez we looked at 9 cars before we found the one he bought.
