For driving temperatures: below freezing: 5W30 Freezing-80F: 10W30 80F and greater: 10W40 This is what the original Toyota Tercel owners manual claims. Though it says 10W30 and 10W40 can generally be interchanged on all occasions, but generally use the 10W40 in "warmer" climates. Toyota dealerships now put 5W30 into the car for oil changes. I asked Toyota service about why they use a lighter viscosity for Southern California weather, and they said the lower viscosity was better to protect an older car from engine wear during cold starts and the 30 was just fine for even the warmer months here. Therefore, I think the newer 5W30 oils are fine as a "general" weight. That being said, I have been advised about *never* using full synthetic oil in my older Tercel, since her life has been on organic oils. Sythetics are so good at cleaning that they might allow older cars to develop "new" leaks around aging seals. Semi-synthetics aren't much better than organic oils in sludge avoidance. In an old Tercel, stick with organic oil unless you get *ALL* engine seals replaced.
is a 91 Toyota tercel e85 compatiable
Single viscosity is high quality oil. Mulit-viscosity oil is used for in the winter.
the redline on a tercel 91 fuel-injected model is 5,200 rpm, at 5,800 it will limit,
dilution will reduce the viscosity The effect of dilution on viscosity of oil is that it will decrease.
How to determine viscosity of coconut oil
The ease with which it flows or how thin or thick it is. the more solid it is the higher the viscosity. As in Oil the thicker it is the higher the viscosity machine oil low viscosity, gearbox oil high viscosity.

hi brooklyn, the viscosity of motor oil is how quickly it flows
What oil viscosity is correct for dodge neon 1995
I don't trust this oil's viscosity.
Viscosity is resistance to flow of oil Viscosity Index is a scale to measure viscosity
the higher the SAE number, the thicker the oil and higher the viscosity of the oil.
