Hey, i have a 94 gt. Last month the car was low on oil and i added 1/2 quart of 10w30 castrol synthetic oil. It had regular castrol oil, 10w30 also. ever since i mixed the two the gauge was getting all the way up to the H, but it would come down. Any idea why this might be happenning? I also changed the oil and put regular 10w30. How can i check to see if its a faulty gauge. Thanks...
