Oil change; mixing different oil grades.

[commissary]

It was time for me to get an oil change today, but instead, I took a nap. Well, after waking up, my mom said she took the car out for groceries and noticed I needed an oil change so went to the local shell gas station to get it done.

I asked her what she used and she said 'Well, I had two bottles of Mobil 5w-20 and a box of Mobil 10w-30. The service guy said it was okay to mix both bottles of Mobil 5w-20 and two bottles of Mobil 10w-30.'

Is this true? Will this mess up my car in anyway?

[PRINCESS PEACH]

don't floor your gas all the time. you're okay w/ mixing oils but.. just dont do it again. stop worrying. just drive. next time, follow the recommended weight from the owners manual.

[omairtheman1]

do it all the time... right now i am running a 7.5- 30 haha

Oh okay, thanks Paul.

[gcretro]

how about mixing 3 bottles of 5 w30 super tech synthetic with one bottle of castrol high milage 5w30?

I decided against it anyway. But curious? (2AZFE motor)

Question for you guys, anyone who answers it and I'll let you in on a secret on how to get 2 gallons of Valvoline SynPower motor oil for $5.

For our 2007 i4 Camry, is it ok to use 5W-30? Manual says to use 5W-20.
I searched for "5W-30" but nothing came up. TIA.

The right answer is--'it depends.' If you live in a cool environment, then the oil is a little thick but isn't going to kill the engine. If you live in desert, and it's summer, then it's just fine. I personally can't see using 5w20 in Phoenix in August.

Mileage will drop a tad using the 5W-30, but I wouldn't be too concerned. You probably won't even notice the difference. In the future I would just stick to the recommended 5W-20 and check the oil periodically. If there are engine problems down the road (I don't really expect any. That's just my anal thinking or Murphy's Law.) Toyota will not be able to deny a claim stating "the wrong oil was used". My 07 I-4 goes through about half a quart of 5W-20 oil in 2000 to 3000 miles. It has done that since new (around 40,000 miles on it now) and I just attribute it to the thinner oil. Not a big concern. I believe Toyota recommends the 5W-20 weight to imporve the fuel economy.

Slight variances in grade or different brands wont make the slighest bit of difference. The only time you have to worry about it is if your engine requires synthetic oil and you put a non-synthetic in, but thats more of a BMW/Merc. highpreformance engine type problem.

It's fine, as others mentioned, you may drop 1/8 mpg in fuel economy, but you won't hurt anything.

Am I too late for the Valvoline deal? I really like their oil.

[touringcamry]

No problem to mix oil. You can even mix conventional oil and synthetic or go back and forth. Just don't put something ridiculous like straight 30W or 75W-90 in there and you'll be fine.

Valvoline Synthetic Motor Oil $0.62/qt AR + tax (2 gallons for $4.98) slight YMMV Valvoline SynPower Full Synthetic Motor Oil - 2 gallons for $4.98 AR + tax/postage at Checkers/Kragen/O'Reilly
That comes to 62 cents per quart! (Before tax & postage.) Synthetic oil often costs $6-7/qt.
This is a high quality synthetic oil & these prices are unmatched in my experience.
There is a slight YMMV, you need a Checkers/Kragen/Schuck's/O'Reilly near you & you need to sign up for Valvoline's engine guarantee.

Here's how it works:
Register your car at http://www.engineguarantee.com/
Select Valvoline SynPower for the 300,000 mile guarantee.
Be sure to use Enrollment Code "ORLY2141" - it affects the terms & amount of rebate for which you qualify. This is VERY IMPORTANT! It's on 'Page 3 of 3' when you enroll, at the top of the page above Make/Model/etc. After you've completed the third page, be sure to 'Click Here for Special Offer' - that's your rebate! I qualified for a $25 rebate with purchase of two gallons - without the code, I believe $20 for the purchase of 10 quarts or three gallons was the best you could do. If you have a higher mileage car, you may not get as good a rebate offer. My car has about 14,000 miles. I also signed up my girlfriend's car & got the same offer.

Next, go to the Checkers/Kragen/O'Reilly near you (hopefully you have one) & buy two gallons of Valvoline SynPower Synthetic Motor Oil for $14.99/gal. I have Checkers in Las Vegas - when I asked the manager, he said all O'Reilly brands should have the same deal until May 25. (I'm looking at the local ad while writing this.) It's on the back page of the ad, in smaller type next to the Valvoline Conventional oil listed for $9.99/gal. You can use the store locator at http://www.kragen.com/StoreLocato...?chain=CSK or http://www.oreillyauto.com/site/f...ocator.oap to find one in your area. Be sure to use BOTH locators as they do not cover the same stores - you may find O'Reilly shows a store where Kragen does not (or vice versa).

Finally, fill out the paperwork, mail in the rebate & wait patiently. It's a very good price for this oil on its own; the rebate makes it absolutely phenomenal.

Here's the final math:
Buy two gallons of Valvoline SynPower $29.98
Sign up for Engine Guarantee rebate $25.00
Total cost before tax/postage expense $ 4.98
Add to the above - Cost of stamp $ .44
Total cost before tax $ 5.42

PS: limit 2 per car, if you have 10 cars, you can buy 10 x 2gallons :d
