Hi-I am new to this board.. I have some oil questions. I apologize up-front for being so verbose. I purchased my wife's 2010 V6 Rav about 2 years ago. with about 65k miles. It was dealer serviced by the only previously owner.. Our oil change intervals have always been every 5,,000 miles. We run a TRD fully synthetic filter and we run Mobil-1 fully synthetic 5w-30 motor oil.. We live in the southeast so we do get climate temps ranging from low single digits in the winter to brutally hot and humid in the summer.
The RAV now has about 80,000 miles. My past few oil changes I've noticed that after about 3,500-4,000 miles we need to add a quarte of oil. I do not need to do this with my V-6 4Runner which runs the same oil but to be fair my job doesn't demand the same amount of driving that her's does so it gets driven much less during the week.
My question is "why the consumption?" It really bothers me when I see low oil levels on my dipstick. There are no leaks anywhere on the ground. Is this a Mobil-1 thing? Does it tend to burn off faster? Is say Penzoil Ultra Platinum a better choice? My mechanic is an old school Toyota/Honda guy that has been in business for years and has a great reputation here in town.. He concedes that fully synthetic motor oil is better pound for pound, but he DOESN'T believe in paying the extra $$$ for synthetic oil and synthetic filters. He says the answer might be to switch to 10-30 conventional and switch the oil change interval to every 3,000 miles with a cellulose filter. I don't know how I feel about that. He's Inspected the vehicle and can't find any leaks or evidence that car is burning oil.
Has anyone experienced this in a your V-6 RAV while using Mobil-1 5w-30 synthetic? If so, what did you do to fix the issue or is this just normal for pretty much any fully synthetic oil regardless of "brand" of oil? In another forum someone mentioned that the PVC Valve might be the culprit. Since she will be due for an oil change in the next few weeks, I will definitely have him check that, but if the PVC Valve ends up not being an issue then I'm not exactly sure what else to do. Finally, am I making a mountain out of a molehill? Is having to add a quarte every 3,500-4,000 miles "normal" on a 5,000 mile oil change interval? Thanks in advance, and again I'm sorry to be so "wordy".
