Question:
I got into a huge argument yesterday with my g/f. One of her mechanics told her that this heavy weight of oil was good for her car. She only drives in the city or down to see me. It is a 2000 corolla with about 80k miles, and it does leak oil apparently. I recommended 10W40 and to switch to a synthetic brand for a couple of months. We live in the Los Angeles suburban area, and the warmest it gets where she is in the summer could be around 105-110, and the coolest it gets in the winter is probably 35-40. Right now it is anywhere from 45-80 degrees night-day.
Thanks!

Read your owners manual. The recommended oil for a 2000 Toyota is 5W30 all-year round. The people who built the car know best.

oil is a hard subject sometimes. it is all about opinion.im my profession as a mechanic, i put 20w50 in most cars with moderate to heavy oil leaks because the thikness of the oil, it is ok to use in hot tempatures. you should just make her get the leak fixed, add reg oil and call it good!

20w/50 is very thick, i live near fresno and i use 10w/40 or 10w/30. any thicker may reduce its cooling abilityMy tackometer goes back and forth?
go by the owners manual on weight of oil, they give you a temp range that is best for the motor, most daily use cars dont like the heavier weight oil, i use 20w50 for my race motor an my 20w40 for my deisel truck, synthetic oil will only make the leak worse for it consistancy is less than pertroleum oil. good luckNot sure what you are looking for in an answer, but here I go, LOL;
Is there something wrong with my car fuse?
The heavier oil weight will leak 'less' from the car due to it's denser viscosity. This is true. At least until the oil breaks down anyway. May also be important to note that the engine will have to work harder to mve this oil through due to it's specific weight and thickness. Not necessarily a good thing for an older small engine car. Especially when it is cooler, the oil will be even stiffer and the starter will have to work harder to turn the engine over.

I would question why the so called mechanic told her to use 20/50 oil first. Then explain to her what this means for her car's engine. If it was to just slow the leaks, you can get other products to temporarily seal the leaks until they are properly repaired. I would suggest you convince her to go with your plans, at least until the problem is repaired properly.

It kind of depends on where your g/f lives and what season of the year it is. 20W50 oil should probably not be used for winter driving conditions where freezing weather could lead to difficult starting and less protection during warm-up. If the Carolla is in good shape and reflects regular care, like fixing oil leaks, you might get your g/f to try one of the more expensive and longer lasting synthetic 5W-30 oils.Taking too long to pick up speed when i accelerate?
NO! a little over the factory oil recommendation is ok, but that is way over the limit. This will just cause lack of lubricity, which will promote faster engine wear.What to spray on car to remove dried bugs?
If the car leaks oil, no miracle additive will fix it! Just replace the leaking seal if you are able, otherwise just leave well alone.
When my friend worked at Midas he once took a nice car for a test drive - with no oil in it. He was doin a change and he just forgot to dump in oil. It was loud as hell when he got back, so he just dumped some 20-50 in it and it quieted down. Unless your car has been used to tow mobile homes and 10000 lb trailers, (or driven like a performance car with no oil in it) your engine won't be worn enough that you need 20-50. Stick to 10-30.
Someone tell me how to adjust the governer on my vehicle?
20W50 is good for the mechanics because they'll get to replace the engine when it wears out. Thicker oil doesn't protect any better, takes longer to get flowing when you start, doesn't flow as well, and doesn't get into the tighter spaces as well. It does raise oil pressure, but it raises it because it's more resistant to flow. You get higher pressure, but less oil. 10W30 Mobil 1 would be perfect for that car.More Questions & Answers ...
